RB 182 FF Cup
i want to buy some different wheels for my 182 FF (with cup suspension) ive been looking a a set from the US but they only do them in 15x8 and 16x8 with ET0 or ET20 i know the ET0's definatly wont wont fit but im not sure about the ET20's i dont want to buy them to find out they dont fit and have to send them back to the US, will these be safe to fit with no modifying bits?
