Humble Rumble's 2012 Legacy 3.6R Build Thread


Recommended Posts

Figured it's long past time that I start one of these. Not really settled on how I want to format this, so this thread, much like my car, will continue to change and evolve as time goes on. Pictures, part numbers, and links will be added as I go.

Shadow Speed HRW Type Rear Window Spoiler came in today! Very impressed with this piece. Nice and sturdy while still completely flexible (weighs about 3 lbs!). Great color and clear, and pretty darn close match to my existing paint. The fit looks excellent too. I dig the notch in the middle too, makes it stand out more from other more standard style roof spoilers. Should also compliment the shape of the Blitzen spoiler if I ever end up getting that on the car. Now I just need a day warm enough to install it (literally double the temp it is now :lol:).

Installed VLEDs VLR-6 resistors in my brake lights. Been chasing some dash warning light gremlins ever since installing my LED brake light bulbs, and I believe these finally solved my issue. I'm a complete wiring novice, so I'm always looking for plug and play solutions. I started with the Alla Lighting bulbs in my brake lights, and they functioned perfectly and performed spectacularly as far as color and output, but I started to get dash warning lights coming on randomly during driving (specifically flashing BRAKE light and solid TCS light). Nothing changed with drivability, no limp mode or anything, and the warning lights would go away as soon as I turned the car off and on again, but I wanted to solve them.

 

Picked up the Triton V6s bulbs, moved the Alla lights into the rear turn signals and the turn signal VLEDs into the trunk, and still got the dash warnings, and even sooner into my drives (about 5 -10 minutes). But the VLR-6's with VLEDs T-Coupler made the installation an absolute snap, literally plug and play, and the resistors are actually super tiny! I was expecting them way bigger. Mounted them on the metal side of the body just forward from the taillights. Pleased to have that solved. :) Recommend these to anyone wanting LED brakelights, the installation takes minutes, is 100% plug and play, and you get what you pay for with VLEDs: excellent build quality and performance.

I'll snap a picture of how I have it setup. The Tritons are pricey, no doubt, but the setup is clean, the wiring is quality, and I can't stress how easy the install was. Only thing is I haven't taken a longer drive yet to see if the warning lights come back after a while, so jury is still out on that, but so far so good.

Any link for those Triton V6 bulbs for us ?

 

 

Audi love for life

 

Check the build list at the top. I'm working on putting buy links for every item that I reasonably can, just added links for both those and the resistors this morning. :) There's also an always active coupon code for VLEDs that's "SUBARU10" for 10% off. Sometimes they have sales with higher discounts too.

just curious as to why you went with the vled ones?... I run these, I had the same problem as you.

in principle they are the same as the vled ones just less expensive and maybe a couple minutes extra to hook up.

Long story short: wiring. I don't trust myself with wiring anything, like at all. I'm literally infant level at electrical knowledge or wiring understanding. Knowing my luck, I'll damage or mess something up irreversibly, and that's the last thing I want.

 

The VLEDs are connected purely with plugs, so it made installing everything super super easy, and all the stock wiring is intact in its original form still. The T-adaptor paired with their proprietary screw-in connectors are what made everything so easy.

I wonder if the quality of bulbs has an effect... Some decent (not vled) bulbs might be low enough resistance to trigger the lights, but super cheap ones might have enough resistance not to?

 

I got the cheapest amazon dual-brightness led bulbs a few months ago, and have yet to have any dash lights without any kind of resistor

it's hit or miss, i've used cheap ones that haven't triggered the x-mas tree, and i've used better quality (phillips) and they have triggered the alarm. It's really a crap shoot.

Suspension installation was completed today! In one word: *WOW*. I've put about 50 miles on since getting the car back. The car feels **INCREDIBLE**. It's like a completely different car. Finally feels and handles like a proper sports sedan, and looks more aggressive too, with a subtle, functional, yet noticeable drop. Flat cornering, better squat on launch, less dive under braking. The handling is incredible and the ride is like driving a soft yet firm cloud that's giving you a re-assuring hug while also giving you a handshake and squeezing *just a bit* too hard on your hand. There is no other words for the ride quality than sublime perfection. I LOVE this setup, and I love this car all over again.

 

Story time: Got the car back this afternoon, and obviously the handling was a HUGE improvement instantly. However, the ride was bumpier than expected, like drastically so. I chalked it up to new springs settling and the Konis stretching their legs. Well, 40 miles later, the bumpiness was getting out of hand, and honestly starting to give me a headache. Things were rattling, even <10 mph rolling was uncomfortable, and by the time I got home home, I was honestly starting to get a bit disheartened. I was starting to fear I had made a huge mistake and the ride would be totally unlivable, and the GF would hate it, and every commute would give me a headache. And just before going inside, I decided to check the adjustment on the rears: BOOM. FULL HARD. BOTH REARS WERE ADJUSTED TO THEIR MAXIMUM STIFFNESS (fronts were full soft the whole time). I backed both of the rears off probably at least 4 or 5 full turns to full soft, went back out again, and instantly: experienced perfection. Smooth, supple, sublime ride quality was at my booty tips. Complete night and day difference. NEVER go full hard on your Konis unless at a track day lmao. Unbelievably relieved that it was something as simple as that, and the ride is no less that absolute perfection now. Could not be happier.

 

Can anyone also tell me how the alignment specs are looking or point out anything that looks off? Alignment numbers are like Greek to me.

Rear camber looks great. Front camber is good according to subaru, but it might be a little more positive than what you'd want if you want optimal handling (it'll save some tire wear how it is currently). Left caster is still factory, right is lower (Mine is too, it seems to be a trend for these cars. No idea why). Toe is good too. I'm jealous!

My understanding of the caster difference is the manufacturer is compensating for the slight angle of the roads. So some cross caster is built into the car to try and negate this.

I'm interested your thoughts when you get the sway bar bushings installed. Car looks great. I really like those wheels on that color.

 

Thank you! :) Will definitely report back. Planning on trying to tackle those along with the Cusco braces and Prothane diff inserts sometime in April. And if I can scrounge the money, I want to do all endlinks as well.
