Well I've re-vamped this setup since I finally had some time to play a little GT4, this setup has really come alive now and is not for the faint hearted. If you're one to wait until the last possible second before breaking this setup will not work for you, take an assertive approach to driving and you'll be fine.
Nice setup, seems to stick to the road well! Have you considered an alternative to the high camber setting in the rear? It occurs to me that its causing a premature tire wear out back. I dont think I will even mess with it though, works fine! Great Job.
