Im soon to be replacing the 18" wheels i recently purchased for a fair whack as there pretty rare £1200, but unfortunately im not liking there 18" size so have decided to replace them with some 20" Rotiform TMB's (9J front, 10J rears Et's 33 &36). now my question is has anyone fitted such a wide wheel at that size to a B7 Tdi before? if so did you have to pull your arches or anything like that? (i will be running Air suspension by the time these go on for the summer.) basically wanting info on any modifications needed to fit such a big and wide wheel? This set of TMB's will be coming off a well known RS4 Supercharged most might know, im just waiting to get back off tour in 3 months to arrange collection and payment etc (these are the only set in the UK). wont be going on until the summer time next year but will be sorting fitting out long prior to that so i know there going to fit.
