Polyurethane Bushings

[e30sky]

thanks buddy

Two things.

First, one thing to remember with offset bushings, is that they do move the wheel forward (towards the front of the car) in the wheel well. Depending on your tire fitment and ride height, this can be a bad thing as far as fender clearance. I'm currently using offset bushings, but am switching back to centered bushings. Treehouse Racing just introduced a centered (non-offset) solid CAB which is perfect for this.

Second, Bilsteins work fine with H&R Sports and H&R Race. I have driven over 200k miles combined on those two exact setups between my two e30's over the past ~13 years. I actually sold my Bilstein sports with over 12 years/300k miles on them, still working 100% perfectly. The shocks are valved well for those spring rates, and are priced well below Koni S/A's.

You can find them almost anywhere that sells e30 parts... Check out some of the forum sponsors. Guten Parts, Blunttech, etc...

well to be honest i want to run some nice 16 x 8/8.5 rims. i saw revshift with their poly bushes so i was thinking the not too harsh one but rather the ones for street performance. so what u recommend, run stock bushes around and run the centered solid or poly control arm bushes? i have revshift in mind for poly and condor speed shop. From what i heard is that revshift is not so gd on service and whats not. u ever bought anything from them? if yes. what is your personal opinion on them

is this the one you are talking about

where would i find them?

1. No, they have had too many issues in the past+ their customer service has been blah from what I have read/heard.
I personally run a combo of Condor Speed Shop and AKG(soon to replace with all CSS)

2. Gain caster correction, I went with Treehouse racing and Ground control camber/caster correction plates.

3. Yes, most setups with coilovers use a camber plate for heavy corrections. With basic springs and proper inserts/shocks, you would not need too much correction. I would just replace old worn bushings with stock and run some Condor Speed shop CAb bushings. A daily will be VERY harsh with too much poly.

Do not run Bistein, they are so outdated. Get a set of Koni sports and pair them with H&R race(nice spring for daily use).

where do u recommend me check for them?

Hey Guys i am about to rebuild my complete suspension set up and i want to go Polyurethane bushings through out.

Question # 1 - are the products from Revshift any good?

Question # 2 - offset control arms bushings, whats the advantage and disadvantage of using it?

Question # 3 - i am not running coilovers, i'll just run the sport bilstein's with lowering springs, is it a gd idea to run offset control arms bushings if i am running that set up?

Thanks

wow...... i did not expect replies so fast lol

i read all your comments and now feel like i am getting somewhere lol, just wanted opinions from ppl who would have done these kind of stuff already. To everyone who replied sry i couldn't reply individually. i did a bit of research and the things you guys said all checks out to be somewhat true. when lowering the car the offset bushings will correct the little issue that will arise. to the guy who recommended condor speed shop i was thinking about them but they are a bit pricey lol, but i am still strongly thinking to go with them tho. just wanted to know if the revshift product works ok

[Herr Faust Schinken]

1. yes i like my rev shift bushings, they make the ride just a tiny bit stiffer but not harsh FYI their shipping takes forever
2. offset control arm bushings are supposed to increase high speed stability, they don't really have a downside on a street car
3. yes, I'm running them on a stock setup

[ak-]

Offset control arms give you positive caster which creates more stability at speed and increased negative TURN-IN camber, not to be confused with regular static camber.
No difference whether you want to run an adjustable coil setup vs. regular coil springs.

Can't answer question 1, I don't have any personal experience.

Question 2 and 3 i feel tie together. From what I know, you will need offset CAB's to correct some of the caster/chamber issues (please correct me if I'm wrong) when lowering. the offset CAB's are usually the M3's bushings (unless if you go aftermarket poly, then they are all solid) and last longer since they are solid bushings as opposed to the stock bushings.

1. Not sure but I've heard of all kinds of fitment issues. I'd suggest Condor Speed Shop.
2. More caster/More caster.
3. Yes.
