Performanceproducts has the so call sport springs for the 16V. Maybe these springs are shorter so they are better mate with the Bilsteins. This just my guess I did not buy the springs or bother to find out the dimensions. Maybe you can try to give them a call to find out, I will probably look into it also. I just have other more serious things on may hands right now.
I would like to get back to the old look of my car, I really hated the truck looking clearances. Let us know if you have any luck.
