According to all info I have found, Moto Metals in the 8 lug format are all -12mm offset (4.5 inch backspacing). They supposedly stick out 2.5" from stock??
Gimmie some more info on these center caps, the ones from Moto Metal are JUNK!I got them too. The only thing I suggest is getting some metal center caps that push through from behind. I got mine from eagle. After working at discount tire for almost 3 years now i see guys coming in all the time to order center caps.
