Not sure what you know about autocross, but in a Contour SVT you would probably not want my suspension. Reason being, it will put you into the Street Prepared catagory, and more specifically ESP. This means you would compete against modified Mustangs and Camaro's. Of course, if you have an off-road y-pipe (you are talking about getting one correct?), you're in that category anyway so you may as well have a better suspension!
I think an SVT would be most competitive in G Stock overall, but the new WRX and the old Integra Type R pretty well dominate that class.
Thanks for doing the legwork on the wheels for me. Let me know whenever you find out.
