I was viewing a post you made a few years ago. I'm interested in your thoughts on suspension on the 986 Boxster S. I've got a 2003 Boxster S with standard suspension that I began autocrossing last May. I seem to have an aptitude and I've been doing well, especially at PCA events. I want to stay in C Street with SCCA. I upgraded the tires and wheels to Bridgestone Potenza RE-71R's on BBS SR 18" (8" front and 10" rear). After that upgrade I began moving faster up the ranks. I'm looking at some suspension upgrades such as M030 springs and Bilstein B6. I'm also signed up for an EVO school in June.
What are your thoughts on the suspension? As I said I'd like to remain in C-Street.
