Rims
 

My 78 03 cabrio runs 7.5x17 et52 cup 2 replicas front and rear. Front tyres are 205/40x17 Avons with stock wings. It runs Kerscher struts with Kersher vented discs with 944 single pot calipers. Camber adjustment is set to max on the strut and track control arms and the tyres still occassionally rub but i can live with it, although i did think about going to 195 size front tyres.
Rears are same wheels with 215/45x17 Avons with stock trailing arms and early 944 rear brakes. Rear wings are stockers that i widened by 1.5 inches. No clearance problems here.
Pix to follow soon.
