[007M]

Okay,

So my M Coupe still has the stock OEM wheels, etc on it. I checked out OEM threads online and it says 12x1.5. So I purchased Muteki SR48 lug nuts. Do I need to purchase lug bolts too? If so, what is the minimum length I should purchase (they are fully threaded). And can anyone explain to me why if I purchased them to fit the oem spec of 12x1.5 why I need to purchase bolts?

Thanks in advance,
Gery
