Hello,
I'm wondering if there is any way of establishing what size stud holes my rotors should be for my vehicle (2011 2.0 tdci). Lots of places say that 13.8mm or 15.8mm can appear on this type of car.
I have measured the stud and that appears to be a M12, so I am leaning towards 1.38mm stud holes, although I am not sure. Anybhelp would be great.
