Hi there, I wonder if anyone knows the answers to the 3 questions I have. My Corrado is a 2.0i 16V Twilight Violet with full Recaro interior and I am in the process of fixing everything, and I mean everything. However when it comes to rims I have purchased two sets and not sure which set to put on it. The first set are Polished 7x16 RH Toplines (4-stud fitment) and the other set are Polished 7.5x17 Audi Comps (5-stud fitment). They are both awesome but I don't know the following:

1) What tyres sizes do I need for boths sets of wheels?

2) What thickness spacers do I need for the RH Toplines? ie what is the 'maximum' before they start rubbing on the arches?

3) What thickness adaptors do I need for the Audi Comps? ie what is the 'maximum' before they start rubbing on the arches?

Cheers, Rob
