My bad on the OZs, I meant O.Z. Ultraleggera HLT although I have now discovered they only do them in 20s which is out.
Agree on LMs, although they are nice, done to death. Dont like the LM-R purely because I dont think wheels with 'a rim' such as LMs, LM-Rs etc will look big enough on a car this size.
OZ Superturismo WRCs would look great on an AW M3 but I doubt they make them to fit. Am checking but I bet they dont.
I think the Breyton GTS is probably one of few options.
