Out here in the far reaches of the 'Commonwealth', few suppliers seem to carry the flat headed wheel studs for 8.4" disc brake drive flanges. And, I see mention that the standard wheel nut studs are not necessarily suitable for aftermarket alloy wheels.
So, what to do? The standard Cooper S wheel nut studs that seat in the rotor are slightly longer than the std 8.4" flange items BUT have a tapered head.
Is there another alternative to the standard 3/8"UNF stud? Or...would the S wheel nut studs be safe to use? Or, Grade 8 3/8"UNF bolts?
