Hi Markus
Do you use spacers on those Compomotives to get them this far out? I use som cheap 8x13" wheels from Bassett Racing with 245/45/13" tyres. Those wheels have 2" backspace (err...at least I think that was the case) and almost touches the arches (it would have if I did'nt hav 2,5 degrees neg. camber). I am looking for something new with slightly more margin. BTW: have you tried wider tyres than 205's?
Regards
Stian
