You say they fit over the 312mm TT brakes, will these fit over standard brakes aswell, mihgt be a stupid question bc i know the standards are smaller, but interseted in the RS 4 reps.
If so, where can i find myself a pair of these with tyres? And what sort of price am i looking on paying? (not getting myself ripped off )
Yep, they will fit fine. Ebay is probably going to be your best bet for a good selection of different conditions and ages of wheels.
