I've been driving around with the PSS9s installed for a week now. I noticed that when i hit a bump I hear a slight knock coming from the front. Is this normal? It sounds like a "clunk". It only happens when I'm cruising. The rears don't make any noise at all. I'll post pics soon.

TIA

Check your front sway bar to start, might be binding at the mounts.

Not normal. Sometimes you might get a twanging sound at very low speed if you crank the steering wheel, but that should be it (this can be fixed as well).

I get the clunk in front too. It takes a big bump to cause it ie: speed bump or driveway curb. I'll check the swaybar and I'm curious about anyone else's experience with this.

I did not get 2 rubber washers with the kit, and from what I understand that was normal. Maybe I am missing something. I will check the sway bar as well. I do hear the twanging sound when i turn the wheel at low speeds. But there is a very distinct "clunk" that was not there when I had the stock setup.

Thanks for the advice.

If I were you I would get the front end checked out...something is loose.

I have had this issue for 6 months since the PSS9's were installed..... After several trips back to the indy shop that did the install and being told that this was normal, I took the car somwhere else to have it looked at (noise getting louder).

Come to find out that there are parts that need to be harvested from the stock mounts (Rotators) and installed with the PSS9 kit. Of course the PSS9 installation instructions don't refer to this... and guess what, mine are missing.

Supposedly the spring is binding up when it's "loaded" and the wheel is turned.... This does makes some sense as the "noise" occurs when the springs is fully loaded and releases..

The car goes in next week... I'll let everyone know if this fixes the problem.

I have pictures if my top mounts, if anyone wants them to compare to thiers PM me, I cannot figure out how to post pictures....

Can you PM the photos, or better yet.......post them here for reference. I figured that the two missing rubber washers might be causing this. I also understand that the US versions of the kit do not come with the two rubber washers (might minimize the noise?). This led me to believe that the kit could be installed w/out them. Otherwise, Bilstein would have included them. But I could be mistaken. Thanks.

My understanding is this...the instructs do NOT say to use the rubber washers from the stock suspension, however if you do use them you will get rid of the twanging sound at low speed when you crank the wheel (I did just had this done and it works). It is a different issue than a clunk when you hit a bump...that to me sounds like a loose mount.

Thats what mine looks like.

While we are on this topic, I noticed that my rear right seems to have more travel than my rear left. I know this because there is more rubbing on the right. From the ground to the top of the fender, they measure the exact same height. Could it be the dampening is not working properly, or is there some difference in travel between each shock?

wross996tt

The dampening should not affect travel only the speed of recovery.

Reviving the thread.....

GT3 camber plates and modified top perches.........

No more noises and 3+ degress of camber on the front

Have you checked and ensured that the right torque was applied on the nuts of the top hats?
