| I know that Lee (GTT Turbo) is a major track head and his car was set up on bilstiens I believe. He had his done by Tony Franks (he does a few of the MINI Challenge cars). Might be worth speaking to one of them on a PM.
I also know Bhozar is a big tracker of his car and I believ he just runs revolution MINI works X coilovers and the GTT braces on his. Don't think he has anything else done except his bishes.... but might be worth PM him as he's very nice guy and always seems ready to have a chat about what he has done.
My car just runs a set of coilovers and all my bushes changed. |
