fenominal

I FINALLY got an 06 OBXT from Rosenthal Acura Mazda in Gaithersburg, Md. Avoid these fuckers like a fat ugly bitch w/AIDS! Im going 2 lower my OBXT, although, I have an 05 LGT for most of the parts Im not trying 2 go as far as the car on this thread. So whats the next best way of lowering my OBXT. Thanks 4 the advice.

Hey man, I'm all over earlier posts in this thread. Take it from me--I've spent more than $3000 on various setups and, at the end of the day, I wish that I would've started with where I am now: just spend $500-600 on a set of JDM LGT SpecB's. DO make sure to add the .5" spacer in the rear, and I HIGHLY recommend the rear LGT LCAs.

Start with that.

If you're curious, send me a PM. I'm near Rockville, off the Red Line.

Did you get it installed Scooby?

 

Also, what do you guys think about an install of this on an otherwise stock XT 5EAT setup? I read through the thread but no mention of that being done. ..

I've used the STI MC and STI BB on my 5EAT OBXT.

I also have a Grimmspeed brace, LGT slotted rotors, LGT calipers, and SS lines.

If this is installed and not adjusted correctly, it will feel like crap. Overall, I DO think it's worth it, but it needs to be adjusted correctly. You don't want 3" travel and no feel and you don't want 8" travel and no feel.

Keep in mind, this is a feel upgrade and not a performance upgrade. If you want performance, just get better pads.

Just to confirm: IF YOU ARE LOWERING YOUR OBXT ON LGT SUSPENSION, DO NO SKIMP OUT ON REAR UCA'S AND REAR TRAILING ARM BRACKETS.

Got mine back today from IAG. It is beautiful and breathtaking and lovely and I couldn't be happier. No more rear sag, no more bottoming out.

More details:

One

Two

I am not really sure what you are looking for. Changing out bump stops and UCAs will give you more travel. If you don't like riding on the bump stops it's an improvement.

 

However, depending on how much you are lowered...it might not be a noticeable improvement.

 

I have Legacy UCAs and bump stops, I have more travel now.

 

Edit: I installed the Legacy bump stops when I lowered my car and the UCAs a few months ago. Day to day driving with an empty hatch I don't really notice an advantage.

 

Recently however, my rear springs don't seem to be up to the task (they are JDM Spec B wagon springs and I am replacing them with stiffer king springs).

 

If I had Pinks, I probably would not need to replace my rear springs.

It seems like you understood me perfectly.

On CA roads, my OBXT did well, but with occasional bottoming out in the rear. Then I moved to DC/MD, where the roads are shiit. I bottom out all the time. Then my rear started sagging more. I've added a .5" spacer. I have less rear sag. That doesn't have much to do with the bottoming out. So I'm thinking about the trailing arms and rear UCA's. While reading through the post, no one really commented whether it had noticeably improved the ride. That's all.

Thanks.

Anyone else?

Gentleman,

I figured I ought to throw in an update, since I have been the most vocal against this upgrade. You can read back a few pages to find my discontent, but I'll summarize it again, before offering my professional opinion:

I didn't feel the money for the booster and cylinder was worth the performance gain. In my experience, the pedal throw became too short, offered no improved "feel," and that the performance didn't actually improve.

What has changed?

I had Frank from Prolific Autosport in Upland, CA, take a look at my car a few weeks ago. He agreed that something felt off, most likely that the booster wasn't working. If you'll recall, I'm an automotive journalist/photographer. I've driven almost 300 cars in the past 18 months, and I'm on record saying my OBXT brakes are the worst feeling and performing brakes of any car I've ever driven.

Frank concluded that the booster and master cylinder were correctly installed, but not correctly adjusted. Something about a nipple, I don't remember.

Upon adjustment, there was an immediate difference in pedal feel. Instead of a stupid short throw, there was actually a decent amount of travel, still a lot less than stock. With the install before adjustment, there used to be no travel and no gradual easing into the brakes. Now there is an acceptable amount of travel, and better yet, the brakes respond to varying levels of pressure. This didn't used to be the case.

Around town, the brakes are easier to work with. They respond to light and hard pressure, and more importantly, to gradual and increasing pressure. This is the good news: they perform as they should have from the factory.

Unfortunately, this is still not great news: the performance still sucks.

I have LGT stoptech rotors and pads, SS lines, and the Grimmspeed MC brace. I still think the best bang for the buck is harder than OEM pads. I'll rescind my disdain for the STI MC/B upgrade as long as it can be done cheaply, and if you know how to adjust it. Otherwise, you'll fall into the trap of thinking little pedal travel is race car brakes, disguising the fact that nothing improved.

In all, I now think that the brakes are passable, if barely, and still toward the bottom of my list. It is an improvement in feel, but not much in performance.

Still waiting on an answer from John Mueller. He's been busy. But according to him, and when we talked in person, he was wondering what was wrong with the brakes. He's the successful racing son of a racing legend. In fact, he was joked about trying to buy a Subaru. Twice. "I never made it past the test drive," he said. Great cars, he said, but flawed.

Anyway, as for the BB and MC, to me, it's the equivalent of cutting your stock springs so the car will be lower and bouncier. I'm still wondering if I've got a bad install, or wrong parts because there's nothing sporty or athletic in my setup.

The purpose for me doing this, and many others, was to remove pedal take up, mush at the top of the pedal travel, AND the sudden ballooning in the braking force that you subsequently have once your pads finally engage. Why? Because there is an ungodly amount of this on most OEM and/or modified OEM LGT braking systems.

 

Negates all feel? Please go into this further. There are three components of feel; pressure, a corresponding increase in brakeing force with the addition of more pressure, and the ability to modulate the brakes at lockup. ALL of these functions, in my experience, were improved apon, ESPECIALLY compared to the severely lack luster OEM booster and master.

 

It may not be perfect, if thats what you were shooting for, but it is sure as hell alot better then the OEM.

Fen,

i fear you are making things a bit worse. you mentioned yourself that you dont know much and dont have the time and you just write. your deduction in describing "feel" is flawed by personal bias. it has no empirical data just your own "i think" and "i feel".

i track my car a lot in Washington. contrary to popular myth we have nice hot weather here and it does rain a lot. often in the same day. track conditions are fun and you get them all. prior to this mod my pedal often went to the floor and in dire straights in hot times i would run out of pedal stroke and loose braking ability. as a side not i do not ride my brakes and i am a very late braker so i dont over heat and toast pads rotors or fluid.

the "mushy" pedal you like or would like is odd in my approach and practice. if i need to modulate my brake pressure i dont want to pump my entire leg up and down 2 inches in a mushy stroke to find the g-spot. i LOVE my slight toe pressing to modulate. even with the ABS i love what this mod has done. i put my foot down late and hard and if a tire doesnt like it all i do is curl a toe for the correct pressure and all is perfect. this occurs at the top of the pedal.

for giggles i buried (or tried to bury due to pressure and instant contact) the pedal and it will overwhelm the ABS and its a slick 4 wheel squeal. so its got bight! and thats with at temp Star Specs.

as for measuring clamping pressure (and/or line pressure) there is a tool for that. ive read about it but dont have one. could be an easy thing to come across.

as for thinking this mod does NOT change pressure you are wrong. changing bore piston and stroke in the MC all affect pressure. also, by not bottoming out stock setup i also dont loose braking ability.

i cant recall now if the STI/WRX MC piston/bore is smaller or larger than stock LGT or if its stroke (length) is different (if someone wants to cut one open or find the spec it would be great). as math would have it a larger bore is less pressure via equal work but if the stroke changes so does the amount of fluid moved by the piston in the bore before moving into the brake lines (again, if stroke changes so does pressure). assuming the mod is a larger bore i might have to push harder now to get increase in pressure but by no longer bottoming out with "mushy" pedal i get engagement 'instantly' and can continue applying more force (aka pushing harder with foot) to increase pressure and push pads harder. this increase in pressure on track pads and wider sticker tires allows greater braking force to be applied before loss of traction. ie i stop faster.

line pressure could also be affected if the brake lines in the LGT are a different i.d. size than the STI/WRX. if they are this would again be an area for math with volume and pressure change that would affect brake torque.

happy braking and here are some fun reads.

triple_B,

Let me elaborate again.

I don't have tools. I don't have knowledge of tools. Until recently, I didn't even have space for tools. I certainly don't have money for tools. I am that guy that has to pay for everything. It's not economical, but that's the way it is.

When I say I don't have experience, or that I lack brake knowledge, what I mean is that I don't know the brake lingo to describe what I feel. I'm certainly no expert on the matter, but from experience, I know when something is good, or not good. But my knowledge is limited to stock function. I can't tell you how long a pad will last on a track, or how long on a track until the brakes get too hot and don't work.

I've driven more than 80 2012-2013 new cars this year (and more than 40 2011's last year). All of them stock, and from the manufacturer. Yes, our '05-06 LGT/OBXT's are now a few years old, and there should be some expectation for regression due to wear and age, etc. But I can say that my stock OBXT was the worst feeling and performing braker among all those cars that I drove. Ordinarily, this could be an isolated incident. My car may have a problem that others do not. But, I found on this forum and on Outback.org, that my brake disappointment is not an isolated matter.

This modification, as I understood it, would better brake performance. I do not believe that it does this. You are correct, however, that empirical data would tell. I don't have or know of a way to do this. After all, even tires will make a noticeable difference. You would need to have an identical setup, before and after, to accurately conclude a realistic sample.

When I describe mush, I don't mean that I like mush. I mean that mush is an actual feeling. There's something there, something happening. Yes, it's not a great thing, but it's a reliable thing in that it's there and you know what's happening. You can count on it and you can adapt to it. With my setup now, there's no indication of any level of brake pressure, meaning, the travel is so waaaaaay short and that there's no feeling from initial clamp to lockup, you have to slam on the pedal to stop at a stop sign, and you have to slam on the pedal with equal force to get it to stop emergency like. See what I mean? With the stock MC/BB, one can casually stick the foot through the jello with just a little pressure to stop at a stop sign, and one can distinguish that, in an emergency, one can stomp on it, to the bottom of its travel, to stop for an emergency. My setup now requires the same hard effort everytime, in every situation.

I drove a 2013 Nissan Altima yesterday for a 5-car midsize sedan comparison that I'm writing. Of the five cars, it had the most sensitive brakes, meaning that it was easy to lock them up, that it only needed a little bit of pressure to stop quickly. If my OBXT with STI MC/BB had the same short pedal throw as it does now, but acted like the Altima, then I wouldn't be complaining. My discontent stems from the fact that performance is not improved, and that brake feel has disappeared. The only "advantage" I see is that brake pedal travel has ben reduced.

The ace up my sleeve (an appeal to professional authority) is that underground racing legend, John Mueller, who last week built me a custom-fabricated coilover to fix my wretched suspension, commented that the current setup and its travel is dangerously bad. As in, something is very wrong. I didn't tell him about this swap, but I did tell him about the new calipers, rotors, pads, SS lines, and MC brace. All have about 4-5k and were installed at the same time.

With that novel said, I believe these are the most plausible conclusions:

1. I have a bad installation

2. I have bad/wrong parts

3. This swap is a bad idea

4. I'm a know-nothing idiot

I would strike out number 4 based on the professional opinion of John Mueller (and his staff, who drove the car separately), who, without my prompting, and without knowledge of the swap, told me that something there is very wrong. When I get the time, I'm planning on semi-interviewing him about the coilover he designed for me. I'll get him to geek-talk comment on my brakes, too.

I hope this clarifies my thoughts, at least until I can get the professional opinion and his professional words.

ok i did the brake swap for my 2.5i legacy. (STI MC and BB). i have a situation that i hope someone could help clear up for me. my brake pedal feels very soft hardly any resistance. when i press down on the pedal its very soft and then about 2-3 inches down my brake pedal stops almost like something isnt letting it compress. My car brakes when i press down on the brakes slightly but like i said it feels like theres no resistance at all in the pedal travel. does that make sense to you guys? i bench bleed the MC and bleed the brakes twice but for some reason i feel it has something to do with the brake booster rod length. When i uninstalled my stock brake booster i measured the rod length and then adjusted the STI booster to the same length. When i installed the STI BB rod to the back of the brake pedal the brake pedal didnt push out far enough to hit the brake light switch that turns the brake lights off. I didnt realize the brake pedal wasnt touching that switch and my battery died. Anyway i had to re adjust the rod and make it longer, but i think thats the reason why i have this really soft pedal with hardly no resistance for about 2-3 inches and then the pedal stops and doesnt compress. Sorry for the long explanation but im not to sure whats going on with my car.

I can't comment on the installation procedure since I'm a tool dummy (I don't have space or tools), but the pedal feel that you describe is somewhat consistent with what I described. The biggest difference is your estimation of the pedal travel (2-3 inches) versus my estimation of pedal travel (.5 inch). But yes, mine feels the same, in what you described, as "no resistance."

It just stops, right?

Agreed, my only agruement against that is that i felt specifically that braking feel greatly improved(imo).

 

If you prefered the feel of the OEM brakes, then so be it, there is nothing else to discuss here.

 

I particularly found the brakes to feel more like a BBK/other sports cars brakes ive had the opportunity to get track time in, and greatly prefered that feeling and how it translated into my braking action while driving athletically/on the track.

Nooo, I HATED the stock brakes, which is why I looked into this. I was confident that LGT calipers, stoptech rotors and pads, SS lines, and the GS MC brace would significantly better both the feel and performance of the brake system. There was a minimal benefit. I again expected a significant benefit to the STI MC/BB mod. The change was significant, but I don't believe beneficial.

Now? I want to drive your car.

^

which basically means, "to each his own." I would rather have some mush and some feel than no mush and no feel.

Fen i directly disagree with you on the opinion that this is swag.

 

Of course changing the master and booster isnt going to provide a stronger brakeing system, this is a very basic concept and the fact that you didnt understand the first go around makes me second guess your general car knowledge.

Swine,

I'm not intending to create a thing. I'm only trying to set the record straight for others such as myself, who maybe don't know as much and who just see "OMG TEH BRAKE MOD IS TEH AWESOMEZ! (I'm NOT a brake expert, but I am a writer, and my intent here is to describe clearly what this mod DOES and does NOT do.)

We could both have the exact same mods, and if installed by two different sources, could have completely different feeling cars. The constant is reduced pedal travel. If that was your goal, then the object is achieved. This mod significantly reduces pedal travel and mush.

I am simply arguing that this may not be a good thing. Obviously, I can't perform a scientific study to actually verify whether one performs better than the other.

In my case, which may not be what others experience (due to variance), I believe that the "feel" in the mush may be better than the no feel in the non mush. If that sounds weird, allow me to explain: mush is a feel. With mine, I could feel the engagement, but it happened low in the pedal travel, closer to the floor. Now, with no mush, there is no feel, no engagement. The pedal simply moves what feels like a half inch, then it doesn't move at all any further. Stomp on it and that pedal isn't moving more than half an inch, and once it reaches that point, it doesn't actually clamp up any better than before. It actually FEELS like it doesn't clamp as well.

As for your three points, it would be nice if we could measure it. But, it is my opinion that this mod a) does increase pressure, but not beneficially b) does NOT increase braking force, c) does NOT increase the ability to modulate.

It simply reduces pedal travel and lessens mush, which comes, in my case, at least, with decreased feel and confidence.

I'm sorry, I mistook the purpose of the swap to mean functional, as in it provides an actual benefit to the performance of the brake system. In that case, yes, the swap absolutely firms the pedal and reduces the length of pedal travel. But it also completely negates all "feel," and I'm wondering if it's actually worse because of it.

I have brand new rotors and pads, both of which are better than stock. They meet the function of my budget and intended use. My point in commenting is to spread the word that this swap is not really an upgrade, that it isn't functional or superior in providing better stopping power, and that it is essentially just costly swag (though some of that cost is saved if you do the labor yourself; I don't have the space or the tools).

My comment serves to inform those, like me, who expected otherwise.

In the future, I'll upgrade to a racier pad to provide what I had originally intended to achieve.

the point of this swap was to firm up the feel, not improve actual braking.

i believe it works as intended.

 

maybe you need better rotors and pads

Hate to burst everyone's bubble, but this mod isn't as great as advertised. I just got my OBXT back from Cobb Socal on Saturday. YES, there is a noticeable difference in pedal travel and pedal firmness, but it's hardly better.

As a quick refresher, I've installed LGT calipers, LGT Stoptech rotors, LGT Stoptech pads, SS lines, Motul fluid, Grimmspeed MC Brace, and now, the STI MC/BB. Short of a full Brembo swap, or race pads, I can't imagine this thing being better than it currently sits.

And it still isn't good enough.

Before the STI MC/BB swap, I was actually getting used to it (wife's car, I only drive on weekends).

Me, From 6/17:

I took my wife's OBXT to Cobb SoCal yesterday. They installed LGT calipers, LGT spec Stoptech rotors, LGT Stoptech pads, SS lines, and the GrimmSpeed MC brace.

 

I drove 80 miles on the OB today and the brakes still suck. To qualify my observation, allow me to say that I'm an automotive journalist and I drive 2-3 different cars every week, and I'm adept at picking out the subtle nuances in every vehicle.

 

The OB still has a long brake travel, the depression is still mushy, and there is no discernable increase in clamping power. That much is subjective, but even stomping on the brakes for a quick start--it still doesn't feel like it will stop quicker, or in a shorter distance than before.

 

*edit '05 OBXT 5AT, no VDC

and

The brake package that was installed included new oil. I did not watch the technicians bleed the system, but only one of the three bottles I bought from brakeswap.com came back to me. So, either they bled the system and added new oil, or they kept two bottles. I'm not that jaded to believe I got ripped off.

 

As for my own car, I drive a WRX Wagon with H6 rear brake upgrade, Goodridge lines, Axxis ultimate pads, and atb600 fluid. I'm happy with the travel, the sensitivity, and what I perceive as clamp/lockup when I depress the pedal quickly.

and on 7/20, in my photo/profile thread:

At the moment, I am waiting on the vacuum hose for the STI Master Cylinder and Brake Booster install. I ordered it a week ago (from this posting) and it seems to be out of stock in Socal. Thanks to Craig, btw, for the details and info related to this install. Hoping for install on August 4, or August 11.

 

In the meantime, allow me to share what the OBXT is like with LGT calipers, LGT Stoptech rotors and pads, SS lines, and Grimmspeed MC brace:

 

For the first week, I felt almost no difference. This is surprising to me, as I really felt the SS lines and GS MC Brace would have done something positive for the pedal feel and brake performance. As I've mentioned in the brake thread, I am an automotive journalist. I drive 2-3 different brand new cars every week. That said, the OBXT has the worst brake FEEL of any car I have ever driven. Statistically, I don't know if it is the worst PERFORMING brake system I've driven, but reports from 2005 indicate a stopping distance of about 160-165 feet from 60 mph.

 

That is unacceptable under every circumstance in my book.

 

This is my wife's car and it is driven city mileage almost exclusively. It will not see a track, despite the hardcore suspension. That is simply how my wife wanted her car to look and drive around town. Yes, she's awesome. The OB is also our family car, since it has a lot more space than my WRX wagon. So, that means it is our road trip vehicle when I'm not driving a new car from work. As much as I'd like to have more power, the tires, brakes, and suspension are more important and practical safety considerations than big time power, hence why we went this route first.

 

Now that the OB has 500+ miles since the brake install, allow me to reconsider some of my earlier thoughts:

 

There is a slight difference compared to the first few miles. Although I am an auto journo, I don't know a lot about brakes to accurately reflect what it is I feel. Also, I only drive the OBXT on the weekends, coming from my own WRX.

 

I feel more friction in clamping power when I step on the brakes. With a casual slowing down to stop at a light, the brake pedal is still mushy and it doesn't begin to clamp until halfway down on the pedal. AFTER the mush is where I feel the increased "friction" in the clamp.

 

When stopping quickly, or suddenly, with hurried but not emergency and medium effort, there is less mush. The bite is more instantaneous, but there is still mush. With this amount of effort, it does get through the mush spot quicker.

 

My own WRX has Autozone OEM replacement rotors, OEM pads, rear H6 rotor upgrade, and Goodridge SS lines. There is no initial mush and they are much more sensitive to tapping. But when I stand on them in greater than medium effort, it doesn't have that friction-kinda feeling. I suspect that is due to the pads since I recently went from Axxis Ultimate to OEM and didn't experience this before. I'm hoping the STI MC/BB gets the OBXT closer to this WRX-like feeling.

So how does it feel now?

There is what feels like .5" pedal travel. There is no more mush, none at all. At the bottom of pedal depression, it feels like the brakes do not clamp. Stomp it harder and nothing noticeable happens except that it feels like the wheels continue to move and the pads aren't clamping. This could be the tires, the pads, a number of different things. But it isn't better than before.

You did all of that and didn't flush the brake system after installing the SS lines? Your symptoms sound more fluid-related than hardware-related. A flush (or reflush if you did it) will likely help. Especially if it was bled incorrectly - LGT/OBXTs are different than Impreza/STI setups. (Per FSM: Perform the operation in order from the closest wheel cylinder to the master cylinder.)

 

Even flushing with fresh Subaru OEM fluid (now on ATE Blue) really tightened up the whole brake system. Adding the Hawk HPS and the GS MCB really brought the system to 8-9/10ths of a BBK. Stops are definitely much more "right-now" than even I thought possible.

The brake package that was installed included new oil. I did not watch the technicians bleed the system, but only one of the three bottles I bought from brakeswap.com came back to me. So, either they bled the system and added new oil, or they kept two bottles. I'm not that jaded to believe I got ripped off.

As for my own car, I drive a WRX Wagon with H6 rear brake upgrade, Goodridge lines, Axxis ultimate pads, and atb600 fluid. I'm happy with the travel, the sensitivity, and what I perceive as clamp/lockup when I depress the pedal quickly.

I don't know how quote multiple replies, so I apologize for this longwinded reply--and I don't mean to threadjack, so perhaps I'll soon start my own picture thread when I get my OBXT on the LGT suspension. Long story short--I did 5 years active army with the 101st Airborne, got out, graduated with journalism degree in 3.5 years, and I found an autojourno job under the largest car magazine in the country...

Back to the brakes, I don't know much about wear. The pads are Stoptech and what I presume are OEM replacement. Do they need a few hundred miles to break in? If not, I'll consider a more enthusiast option at replacement.

On a side note, from the two people I met at a local meet today who's done the Grimmspeed Master Cylinder Brace mod, they said it made a tremendous difference in brake feel. They swear by it.

I took my wife's OBXT to Cobb SoCal yesterday. They installed LGT calipers, LGT spec Stoptech rotors, LGT Stoptech pads, SS lines, and the GrimmSpeed MC brace.

I drove 80 miles on the OB today and the brakes still suck. To qualify my observation, allow me to say that I'm an automotive journalist and I drive 2-3 different cars every week, and I'm adept at picking out the subtle nuances in every vehicle.

This STI MC/BB upgrade will be next for my wife's OBXT.
