i was only able to find +20mm studs and as for milling discs down i used Hi-Spec motorsport as they are across the road from me, very good service and bout 25quid a disc i think, took mine down to 260mm
tbh Phil i wouldnt really care what a knob sack like that who buys a pre-modded car and just wants to race thinks, your a ledge we all kno that u have nothing to prove
