I've been co-driving and working on setup in a Roadster for 3 seasons now and I feel like I'm finally getting to the point where the car is quick and playful around the cones, so I thought id share my setup and hopefully start a serious discussion about autox setup and driving technique for this car. I've also been petitioning the SCCA Solo Events Board (and failing) to move the Roadster from SS to AS class where I think it'll be more competitive, and to allow the Roadster into the CAM classes so modified Roadsters have a class to compete in.
