I inadvertently bought 255mm rear discs for a 2.7 and think 3.0 tdi. It seems no one wants to buy them off me, so I was wondering if the 2.7 and 3.0 tdi uses the same rear caliper as the 2.0 140 tdi's, and if so if I got hold of a set of 2.7 or 3.0 rear caliper carriers would I be able to use the 255mm discs on my 2.0 tdi?
