Thanks a lot, Dave! This really helps.I did a bit of quick research:
Read The Book: Solstice Performance
If you want to learn more about building a road racer Pontiac Solstice, check out the new technical build book from Pontiac, Solstice Performance (GM PN 88958697). Out in October 2007, it provides details on how to upgrade a Solstice to meet the Sports Car Club of America (SCCA) racing requirements, how to set up the chassis, and tips on how to go fast at the racetrack. There are more than 800 photos that show the details for creating a fun, competitie Solstice road racer.
From the SCCA GCR: For Pontiac Solstice in class T-2:
Detachable hardtop GM part #PCS-0664 shall be installed and convertible top shall be removed. Suspension option ZOK and Rear Spoiler (D52) allowed. This max tire size supersedes TCS 9.1.10.D.7.b. B&M cooler #70298 and Weldon Series 9200 pump may be used for differential and/or transmission cooling. The mounting and wiring associated with the installation of these coolers is unrestricted provided it serves no other purpose. Ron Davis radiator part #1-38S006 allowed.

When I have tried to find anything in the GCR, I usually search for about an hour, then just give up.
