Does anyone know off the top of their head what the bolt pattern measurement is for our regals? I'm thinkin about buying some used wheels to throw some drag radials on so I can go out and get me a time slip. Any one know what the measurements are? I see measurements like 5x4.5 but am not sure how they get that measurement, anyone know? (I'd go measure mine but its dark and rainy and I don't feel like walking out to the garage.) I'd rather sit here and drink colds ones!
