A bump and a question. What is the difference between PSS9s for C4/C4S and C2/C2S (all wheel drive vs. rear drive)? A friend got a set of used PSS9s from an RLer's C4S and is about to install on his C2S. We sent them to Bilstein, had them dyno'd and repaired and just wanted to make sure this won't be a problem before "digging in".

Thanks.

Tim,

They will fit perfectly; there are no differences.

Are the spring rates slightly different to account for the slightly heavier front end of a C4?

Thanks for the quick reply Steve! Much appreciated.

Is there a huge difference between the p9 and p10?

Martin S.

What I am hearing there is little difference between the two, other than the PSS9 has 9 clicks of adjustment, the PSS 10, has...you guessed it, 10.

I have had PSS9s for years, wouldn't trade out except to go to the Steve Weiner trick shocks or Motons, or????

There is only 1 set of PSS 10 for the 993 GM5-D268 48-132688

As Martin says, the PSS9 had 9 settings, the PSS 10 have 10 settings and "click" in each position, the PSS9 dont "click"
