With the low ride height, aero and wide 335/345 Hoosiers on our GT we tried a few different rates beyond our standard 650/250 rates. We incrementally went to 800 up front and 350 in the back. After some more testing and back and forth with the rear rates we settled on 275. The 350 were bad and the 300 weren't quite as fast as the 275. We've got this same setup on a customer's dedicated autocross car on 315 Hoosiers and a deep rear spoiler (no wing allowed) and they are working great.
