Can somebothy tell me if the following setup will mount under my 1303 1979 "vert"with stock fenders:
944T front suspension with 4 pot brembo and vented T disks;
944T rear suspension with early alloy arms, brembo's, vented T disks;
front 7x17 et 55 with 205x40x17 porsche rims;
rear 8,5x17 50 et with 225x40x17 porsche roms.
If stock fenders will not fit what size fenders I shoud buy?
