Since I can't seem to locate a separate "996 Classifieds" forum, and I don't know if visitors to this forum look at the "911 Classifieds" for 996 parts, I am posting a link to my 996 PSS9 for sale on the 911 Classified forum.
This PSS9 suspension was un-installed by me when I sold my '99 C2. As I had no hope of recovering any of the cost of the suspension upgrade, I removed it. It was a great improvement in the handling characteristics of the car.
