There's a place called Cars & Concepts just off Dale Mabry, south of Hillsborough. They specialize in BMWs, but I went there to have my friend's RX-7 aligned, and there was a stroked S2000 and a nice EVO in the parking lot, as well. Seemed like a cool guy running the place, and I know they have a nice reputation. I plan on taking my car there when it's ready.
Forgot to mention, they frequent the race track, so are no strangers to setting up a car for cornering.
