Great thread. Thanks for starting it. I will be in the market for an updated suspension at some point in the future so this is great info.

Here are my answers

0. Which kit do you have?
Ground Control Coilover kit, with GC camber plates. 600 in.lb rear springs, 440 in.lb front springs
1. When was the kit installed?
March 2011
2. How often do you track?
10/12 times a year. Kit has seen about 24 track days
3. Run group?
Advanced
4. Any major issues? Rebuilds?
No
5. Other minor issues?
Creaking noise after initial install. A quick call to Ground Control identify an incorrect install. There needs to be a small space between the endlink sleeve and the spring lower threaded perch. Corrected install. Not issue since.
6. Would you recommend it to others?
Definitely. It is a nice system for a combination street/track use that maintains the stock EDC shocks. It does not perform as well as a real setup (like dawgdog's above which I can confirm changed the character of the car) but nice nonetheless.
