Will Porsche wheels fit an Audi A4? Has anyone had any problems with Mille Miglia MM11-2? I have heard that they are light but not strong enough for track events. What about SSR Integral wheels anyone know strengths or weaknesses.

I don't think Porsche rims will fit the A4....I believe the Porsche rims have a 5x130 pattern, where the A4 has a 5x112 pattern. Check out www.1552design.com they have H&R adapters for such a thing.
