the 17" rims I have on the R are too heavy and tbh are very tatty atm. I'm looking at getting some 16" lightweight rims.
I need to know what ET or rim fitting I should be looking at as I have no knowledge on this whets so ever. I have 310mm willwood discs on them.
Car only used on roads no track etc. (not sure if that makes any difference)
Any advice would be greatly appreciated
