I have had Bilsteins on my car for almost 4 to 5 months now and didn't notice much difference with these things. Who is running coil overs on their C5 and which ones did you go with?

Many coil-over packages avail. Why are you considering them: street use only, HPDE, serious road racing?

Depending on your use would impact how you might choose:

Moderate price/street performance/hpde: LG, DRM, Pfadt

Higher price/RR oreinted: Moton, JRZ (2 or 3 way adjust)

I think that you would have to get out of the regular shocks and into a coil over before you would really notice a good difference with your shocks. Although I have heard alot of good things on the Koni FSD's:party:
