I run my tc5 on carpet in the stock rubber class. My local track is low traction, but I can't seem to loosen my car up enough. When I have went to high grip tracks it just traction rolls. I run the stock chassis and the best it has worked for me was with copper and purple springs. Everyone at my track tells me I'm too stiff. If I soften it up it just seems to have to much bite. Any ideas?
