Sparesbox are having a sale on brake upgrade parts, so I thought I'd look at replacing my rear rotors of my GT Sport 1.4 TSI (125). RDA 7911 at 258mm and RDA 7912 at 286mm both list as compatible with my vehicle. DBA list several different sized rotors from 252mm to 286mm as fitting.
It's a lot of effort to take the rotors off just to measure them. Can anyone please shed some light on which are the correct parts/sizes?
