i have a p1 with the prodrive 18" upgrade wheels but i am thinking of a set of 18" khan rsr wheels after seeing a v5 with a set on. does anybody know what width and offset the 18" rsr khans are and will they fit my car with the 225 35 18 pirreli p zero tyres i have with out fouling the arches, also will they clear the 6 pot ap,s i have fitted.
any information will be a big help.
