So I want to put some new rims on the 1986 5000 CS Turbo... It has the gold BBS rims on it right now and the guy put semi-low-profile tires on it. I am not trying to spend a fortune, but I would like some rims/tires larger than what are currently on it. How can I find out what size rims I can use and what size tires? I'm also thinking about tinting the windows! Hurray for pimp'd out Audi's!
