C2- 1999 Porsche Factory Suspension

Recommended Posts

Loren, I had the wheels off to get new Conti2's mounted in the rear . I checked the part number on the shocks. Here is what I could see:

p# 996.333.055.20

Description: USA Coupe Schalt Sport

Date 05/05/99

Number 1499472.

Is this the shock for the M030 US or is it ROW 30?

Appreciate insight.

The shocks don't make a sport suspension - the springs do. You need to find the color bands on the springs. There will be three color bands - the first two are spring type and last one is tolerance for the spring plate. They will likely be brown and white (standard springs) with a tolerance color of green or white. So your colors may be: brown/white/white.

Tell me the spring band colors and I can tell you what they are.

996.333.055.XX is the part number of USA standard rear shock. The following link explains more than the average person should know about the 996 suspension options.


One other way to determine if your car was ordered from the factory with the M030 option is to look at the option codes on the sticker under the trunk.

Do the pss9's stay aligned well. Also how is the ride on those, compared to the RoW sport or USA sport suspension? So I hear the RoW sport suspension is as good as it get's for the best of both worlds, daily drive and autocrossing. One time I put adjustable coilover shocks on an RX7 and it was a real tight ride.
