i'm martin from germany, my english is not the best one, so sorry for that.
since last year, i plan a supercharger and so, i have to change some parts, the exhaust system is at 3" and since a few months the brake system is also changed.
is a brembo with 323mmx28mm discs.
to see on the picture, absolutly minimum is 17"...it's nearly the rims, so 18" will be better.
