Why not go 6mm All Round and Grab a 200mm HPI Skyline, Supra or RX7 body .. The 6mm Offset will allow you to fill out th guards nicely
Or is This more for your Enzo?
As I think the Stock rims you have now have 3mm OffSet as it is

(I dont like Black rims, its a personal Choice, Black rims go well with White cars just I dont like them on any others)
