correct backspacing / offset???
I've noticed several places where people mention using a 50mm offset with the ZR1 wheels...is that correct for *any* 17x11 wheel?
If I'm ordering a custom-made set of rims, is the offset and lug pattern enough information for them to be made?
Also, since I have your attention, is 56mm the right offset for 17x9.5 wheels on the front?
thanks in advance,
Shane
