I know that the Bilstein coilovers use H&R springs and the H&R coilovers use Bilstein shocks, but the Bilstein rep at the NE aftermarket event told me that the Bilstein units have different specs(spring weight, shock dampening etc) and are different from the H&R's. Obviously they are not like comparing a Bilstein coilover to a Koni, but he mentioned there were differences.

Do any of the Bilstein PSS users have the nasty rear camber problems like the H&R users?

My coilovers arrive tomorrow and will be installed on Monday after work. Any tips/suggestions?

Thanks!

I forgot the name of the company but a different German Spring manufacturer fabricates the springs for Bilstein.

The differences are both in the front and the rear of the car.

The way the front helper spring attaches is opposite of how the H&R helper spring attaches. Bogey and I went through this when I did Mike's PSS9's. The rears are also different in how the lowering piece works. The H&R has the piece on the top and the Bilstein has it on the bottom, or vice versa! lol I forgot which was top and which was bottom. Overall they are not the same at all.

I do not know what the spring rates are nor do I know the size of the shock tubings or if they are even close to being the same.

The PSS9 kit is not even close with the shocks since they are adjustable. I have not seen a PSS Bilstein kit so I can't comment on that.

Setting ride height to it's highest point is the only way to minimize problem w/o going to a kit such as Griffith's or slotting like Brad did.

Obviously the shock internals and springs might be different.

With Mikes install were there any camber issues?

Are you sure they don't use H&R springs? The Bilstein rep said they do, but he might have been clueless.

Do you think the Bilstein setup(having parts in different places) is better, worse, or it doesn't matter?

Thanks Lar.

this the camber will be nasty like those inital pictures of Brads TTR w/H&R's?

Larrytt

He will be getting the rear control arms from Griffith's.

I was told the name of the spring manufacturer and never heard of them. But the springs are not H&R, unless it was/is being changed to H&R now.

I have not looked at a set of H&R's in person other than on Cliff's TT and I only drove it for a short distance. So I can't compare the setups at all. Don't know anyone with coil-overs other than Mike and Eric and they both have PSS9's.

Shoot me an e-mail . . .

Larrytt

but I do not have the same camber issues that Mike has in his TTR and we are lowered about the same. My rear tire wear is normal for ANY car, not just a TT.

I have a feeling that something must have been changed in the suspension geometry somewhere along the lines for all of the newer cars to be having camber issues and excessive tire wear. We have each put 30,000+ miles on extremely lowered cars! Do you have a camber issue? I don't.

I meant with the coilovers, not springs...

Colonel Bogey

were of his car on frozen and broken adjusters. The broken adjuster caused his ride height to sink further resulting in the extreme rear camber. Install of revised adjusters solved problem.

If you set your ride height on the PSS (or H&R coilovers for that matter) to same as you presently have with H&R sport springs your rear negative camber #s will be identical. Suggest you take careful measurements of your car with present set-up including front and rear camber if you have access to a gauge. Also, document ride height from bottom of car to ground in a number of locations.

I found that -1.25* front, -1.8* (outcome) rear camber, 0* toe front and rear (small adjustment IS available for rear), 1/4" nose down rake (as measured from center of wheel to fender arch - maintains high speed stability) and corner weights within 10lbs front and rear was perfect on 180QC.

Find rear height first, adjust front ride height, get close to front camber target, do corner weights, fine tune rear ride height (even turns each side), fine tune front ride height (even turns each side), fine tune front camber, recheck corner weight (with your weight in car)...was the best order of things in setting up car.
