I've reached a point with the car where it's becoming obvious that I need a rear downforce wing. If I up the boost just one psi, the car fishtails across the finish line. Bring the boost back down that one psi and the car sticks and is a joy to drive. It's time to build a rear decklid wing. Anyone out there have any experience with this, and can you add any design points to avoid? Any trick features to add? I want the wing to turn out bitchin. Any pictures of great spill plate designs that work with the body lines of our car welcome.
