Hi I toying with the idea of lowering my van. But unsure what wheel to go for. I like the idea of new rs4 18". I know they fit and you can lower but one of my mates have had problems with them rubbing. I looked on ETKA at work and EPAC and for my age van all the alloys are et 42 but i was reading the guild and got abit confussed. So is it best to go for the 17"????? My dad run 17" on 235/45r17 fine I know there abit out but thinner tyre allow the stones in the lane to scrach badle. thanx for any help.
