Got a bit of a dilemma. Got some BBS CH 18" x 8.5 et35 that im thinking of selling. They do not fit well on my B5 s4 saloon, i get slight rubbing on the front passenger arch at full compression, ie when taking a tight corner fast. Took it down to QST who fitted some H&R coilovers (what a transformation), they told me that s4s passenger side wheel sticks out about 5mill more than drivers side. Apparently this is quite common, i was shown another yellow s4 with the same problem (that didnt have 8.5s on though so it wasnt sticking out past the wheel arch) Anyway, a few options have been offered up as a solution to the rubbing. 1. Roll the wheel arch 2. Lower profile tyres up front 3. Change my alloys for less wide ones Dont really like the idea of 1 but have not ruled it out. Dont mind doing 2 but what if i get a flat, what tyre should the spare have? I see 3 as the last resort, unless i can get a good price for my hardly used BBS CH with goodyear F1s. Any suggestions or comments would be much appreciated?
