I purchased these parts several years ago. They were intended for my 2007 LGT but I never used them. Both are still New-in-box, never used.

[sOLD] AVO Solid Boost Actuator; $100 shipped.

I was thinking of using the kyb gr2s with the eibach pro kit. Does anyone have any experience with that setup? I like the drop with the eibachs(in front .8in rear) if that combo isn't good what struts would be better suited for the eibachs?

Just went that route myself. I've had the eibach pro kit with stock struts for a couple years - loved it. I just replaced my struts with kyp gr2s. I think they are supposedly rated at about 15% stiffer than stock and based on the feel of my car, i believe it. They are slightly stiffer and at first I thought they were just past my preference level. After a few weeks I have gotten used to them and have decided that they are a perfectly fine alternative to the stock struts.

I was really careful to choose a balanced compromise between daily driver comfort and a step up in performance. I still think that the Eibach/stock strut combo is my favorite but the gr2s won't upset you if you want the same thing as me.

So how are the Eibach's holding up for everybody in the long run? I'm looking at getting some for my 05 LGT. I want a bit of a drop, but not too much as its a daily driver and I still want some comfort. Thinking of putting these on my stock struts, running about 90,000 kms currently (55,900 miles) Whaddyasay?

I wanted exactly what you are describing. I put Eibachs on stock struts and got exactly what you are describing (I already had cobb sways which are great too). The struts had about 20k miles on them when I installed the springs and I have put about 20k more and they are fine so far.

Well… During the 5 days or so I have had them on they have made this creaking noise over bumps, the noise come mostly when the suspension gets slightly unloaded… Only from the rears, and mostly from the passenger side... … Just took off the rear wheels again today and checked everything, made sure everything was nice and tight, and that the springs were sitting nicely after the break in period (5 days about 500 miles :] ) ….

 

 

 

Any advice people?

 

Thanks!

Same thing happened to me. I had the bushings on my cobb sway bars greased and the squeaking disappeared for a few weeks. It is slowly coming back. I may have to have them re-seated and maybe even upgrade the endlinks.

Ya. The car barely leans at all. It's sooo much faster in the corners. And for just springs you can't complain at all. I recommend these springs for sure. I think it's the beginning of this thread where bosco swears by this setup. He has had coilovers. Pinks on bilsteins. Etc. He likes eibach on stocks for the perfect dd. I completely agree

Yeah, this thread including Bosco's comments was one of the main reasons I chose this setup.

For anyone interested here is the info on the ground control bumpstops:

This is an email I wrote about cutting them:

> I have a question regarding your soft progressive strut bump stops. I have a 2007 Subaru Legacy GT. I plan to install Eibach pro springs over stock struts/shocks. The LGT front struts have about 7cm available bump travel, 6cm of which includes the stock bump stop (jouncer). The Eibach springs will lower the front of the car by ~2.5cm meaning the stock bumpstops will be compressed a full 1.5cm at rest. Your strut bumpstops are appx 5cm so even though they are shorter they will still be compressed about 1/2cm at rest.

> What is your advice about cutting the ground-control bumpstops? I am thinking about cutting off the bottom progression and keeping the top conical and mid flared-out sections resulting in a bumpstop appx 3.5cm. Could you please explain why you would or would not recommend cutting the bumpstop?

> Sincere thanks,

and the reply from GC:

No problem,

Cutting any bumpstop is common practice to gain lost bump travel. The key is not to cut so much that they will be ineffective. We suggest cutting the bottom portion of the progressive bumpstops if the car is lowered enough for it to be advantageous. Cutting the bumpstop too short will result in another component becoming the limiting factor, usually the spring which will coil bind and quickly ruin the spring, or in extreme cases the piston of the damper itself can be destroyed by plummeting to the bottom of the damper body.

feels like its on rails with stock struts???

I'd call it a noticable improvement and great for a daily driver but I personally wouldn't quite go as far as saying it corners like it's on rails. I already had cobb anti-sway bars but I still noticed an uptick in cornering performance and I definitely noticed a significant improvement in squat and dive reduction. I think it's a great modest suspension upgrade.

Hanslo

More info on your bump stop swap please? Pictures? Easy to do? Where did you buy bump stops? etc. Does this make a noticable difference over just the springs? I assume this is just to prevent hitting the bump stops, or are they stiffer?

This thread:

http://legacygt.com/forums/showthread.php/tein-h-techs-really-good-substitute-eibachsi-121163.html

talks about the eibachs and equivalent. I posted in there a lot. See posts 72 to 86 for some observations and pics of the bumpstops.

In this thread:

http://legacygt.com/forums/showthread.php/blistein-hd-bump-stop-mod-99244p3.html

I describe my experiences with cutting and replacing the bumpstops. Read from post 68 to the end.

I'll have to find you the info about where I bought the bumpstops. You can probably google Ground Control soft progressive to find them. I originally got info on these from this forum but I can't find it now. I'll also see if I can find my email from Ground Control with advice on where to cut their bumpstops.

Just the stock lgt struts here

Same here, Eibachs with stock struts. I also replaced the front bumpstops with trimmed ground controls. Virtually no sacrifice in comfort but noticable reduction in lean and dive/squat. I love it.

Hey Folks,

 

Tire Rack is having a sale on Eibachs. See below

 

 

Holiday Rebate Offer

Offer valid on any new Eibach Pro-Kit Spring Set or Sportline Spring Set purchased from in-stock inventory between November 16, 2009 and December 31, 2009. Read all offer details here.

Unfortunately not for the legacy though. They have been discontinued and are not available anymore. It looks like the impreza folks can still get them.

Nothing scientific I didn't even notice that the ID changed... It just seemed to me that if I want to delay engagement with the bumper while still providing as much remaining protection to the strut, that getting rid of the small end of the bumper would be best.

 

I trimmed half of what you did, just taking off the smallest "donut".

 

Given that I dropped a bit over an inch and trimmed less than an inch off the stops, I think I just reduced the total travel less than if I hadn't trimmed.

I'm likely going to be at the break even point on the front by removing about 1 to 1 1/8 inches of bumper but then reducing the travel by about 1" with the Eibach's.

I kept the softer half of the bump stop thinking that if I hit it, it will compress a fair amount and give me another 1/2" or so of travel and a progressive bump. The firm half would not compress much and give me a much more abrupt bump. I'm worried that the softer half will get chewed up since it sits loosely on the strut. If only it was snug like the other half I wouldn't be worried at all - grrrrr:mad:

Hanslo

P.S. I think i'm going to look around for replacement bump stops. I want something that is significantly shorter than our stockers but designed for progressive compression. Any recommendations?

Thanks

I swapped springs on my spare suspension assembly. I put Eibach springs on stock struts/shocks in preparation for my suspension swap this Thanksgiving weekend.

I trimmed the bump stops on the front struts:

Pic1 shows the stock bump stop. Pic2 shows what it looks like after I cut it. I had a hard time deciding which half to use. Pics 3,4 show how I cut it roughly in half. The half on the left is about 1/8" shorter but much more firm. Pics 5,6 show how much I could compress them with my thumb - I could hardly compress the shorter, firmer half at all.

I decided to use the softer half since, if I do hit the stops going over a bump, I don't want it to be too abrupt and harsh.

Unfortunately, the internal diameter of the stop isn't uniform. I didn't realize this until I had already cut the first one in half. The softer part has a wider internal diameter - about 9/8" compared to about 7/8" for the firm half (see pics 7,8) which allows it to slide and spin freely as compared to the other half which fits on the shaft snuggly. More unfortunately, the bump stop is what holds the dust cover up. Since the softer half of the bumpstop is free to fall to the bottom of the shaft, the dust cover does too. I ended up using a foam gasket/o'ring from a CD spindle case as a washer to hold the dust cover up - terribly ghetto but effective. I don't know how long it will hold up or if it even matters. I also hope that the bumpstop doesn't get completely chewed up due to it being loose.

gk1, you trimmed off some of the softer end that has the larger internal diameter. Did you do this on purpose for this reason? I didn't realize the internal diameter would vary like that. Has anyone else encountered this? Will it matter? I'm thinking about putting the other half on instead. This will make the bump stop function like the original as in it will sit snuggly and stay in place. But then i'm not sure what I have gained. I will have removed the softest, squishiest part and left the non-compressable part in place.

Thanks,

Hanslo

OK, so I have looked back and can't find anyone with Tien S springs and Koni combo so does anyon have info on this set up. New to posting but have been lurking for some time. BTW this set up is sitting in my garage now. Stop me or push me. 05 LGT limited wagon. Cobb sways, and AP:eek:

I have the cobb sways and AP myself and love them. I have read nothing but good things about the konis. IMHO it's the S-techs I would reconsider. Of course, it absolutely depends on what you are after. From what I have read I believe the S-techs are more cosmetic than performance oriented. Again IMHO, I would look at almost any of the other springs commonly discussed on this forum over the S-techs. (I am not talking from personal experience).

The stock front bump stops look similar to the ones in this thread:

 

http://www.rs25.com/forums/f9/t76419-bumpstops-you-riding-them-picture-thread-measurements.html

gk1 that was a great read. I read the whole damn thing and next i'm going to read the thread by 'stretch' linked in there.

I'm a little surprised there isn't more talk on this forum about trimming bump stops. Unless there is a good reason not too, I fully intend to trim the fronts when I do my install. I'll have to exam the rears some more since it appears that it may not be necessary to trim the rear bump stops.

For those who have already installed their suspensions, read the thread provided by gk1. It explains how to trim bump stops right on the car without having to disassemble anything. Since the discussion is about the Impreza RS I don't know how well everything applies but it might.

Thanks,

Hanslo

Hanslo,

When I had the springs installed by my dealer they did not say anything to me about cutting the bump stops to ensure proper fitment. They told me the job went smoothly, just broke down the stock setup and reinstalled the Eibachs.

Hey Bovesnh1. I'm sure it isn't required for proper fitment. I know you and others have been quite satisfied with the feel of the ride so it probably isn't necessary at all. I'm just thinking that if it can be done it might be a relatively harmless thing to do to regain suspension travel lost by lowering the car. My plan is to trim about 1/2" off the rear stops and maybe an inch off the fronts depending on what they look like.

gk1, what do they look like? Are they similar to the ones pictured in this thread?

I was under the impression that the bump stop mod was for BIlstein /inverted type struts only. I didn't do it for that reason but have had no issues with IONS and the Koni's. Previously with the stock struts and Swifts it was Boom, boom pow over any bump bigger than a 1/2 inch.

That is the impression I was getting from the other thread too, but...

Posted by gk1:

I'm running ion springs with stock struts, and I trimmed the front bump stops when I did the spring install. Can't say that I can tell a difference, but that might be proof that it helped...

...With the top hat removed, take off the boot and then slide the bumper off the strut shaft, cut part of it off from the small end (I can't recall if I cut off half of the first small "donut" or all of it), then put everything back together.

Posted by scoobydoobie:

I put forester specific Tein H.techs on the stock struts of my 99 forester a few years ago and cut the bump stops on the stock struts.

...It looks like it can be done. I have attached pics of stock LGT struts and blisteins for comparison. To my untrained eye they look a lot like the same general construction which is why I am thinking it is possible.

[i grabbed these pics from other threads, so thanks to the members to whom these belong]

Hanslo

I keep forgetting to ask. Has anyone trimmed the bump stops on their stock struts? I have seen the walkthrough for trimming the stops on bilsteins but what about stock LGT struts?

KurtP, bosco, bovesnh1 you all have run stock struts on Eibachs right? Did any of you guys cut the bump stops?

Thanks,

Hanslo

Looking forward to seeing some pics

Or the Tein H-techs. I have a thread going called "Are the H-techs really a good substitute for the Eibachs" in the suspension forum. The conversation has started to include the ralliteks as a possibility too. Check it out.

I have called Tirerack twice now about this. Both times they told me that they are discontinued and out-of-stock even when I mentioned that thier website says special order. I have also called about eight other vendors and all say discontinued out-of-stock.

Did you run the 225/45 on specB rims with your stock suspension or only with your Swift and/or Ion aftermarket springs? Are you saying that I should be ok with the Eibachs or are you saying that I should be ok with 225/45/18 on my stock suspension? I know the specB owners often upsize but I thought that was because they had different springs.
