I installed PSS9 coil-overs last week and the ride and handling is better than expected with one problem.

The rear feels "bouncy". I have it set on 1 "hardest" in the rears but I still feel like it should be stiffer. The back end bounces when I go over a rise or through any dips. I am at -.5" drop from stock.

I have a tip. Should I be using stiffer springs in the rear to accommodate for the extra weight? If so what should be the correct spring and what comes in a "standard" PSS9 kit?

 

Try other settings and see what that does. Could be the adjustors are not working. Seen it before.

 

The adjuster had to be taken apart and then reassembled on top of the mounting plate after the springs were pre-loaded. I took considerable time to ensure that all was done exactly as described. I thought that this was a touchy deal especially since the instructions sucked from bilstein.

Is there any way to determine if they are correctly installed and function as intended?

If they do not work what are the options?

Thanks!

 

I have an 04 tt and same issue. Thought it was in my head.
