In the next few months im going to do the 312mm front brake disc conversion on my A3. All it requires is new caliper carriers from the likes of new TT, or MK5 Golf GTI etc etc, new 312mm discs and new pads. Thing is, im not sure weather to go with OEM 312mm discs and pads or aftermarket. If it was to be aftermarket, what would you recomend to me? Thanks.
