I think that the op's question was a valid one.When changing wheel/tyre sizes there are many possible problems.Like the tyres rubbing or bottoming out etc.Its not just a case of slamming them on.I ordered my sline with 19" rims.This meant that the sline suspension had to be 20mm lowered and not 30mm with stock 18".He had every right to ask that question.I think that when jeremy clarkson refers to audi drivers as cocks, i think we know what he meant.
