I have a set of 17z calipers that I want to trade for some 18z's. These came off of a 07 Touareg. I was going to put them on my C5 A6 but I bought the 2 piece rotors from ECS for the B7 S4 so I am trying to cover these 345 mm rotors and the 17z's won't mount up and after some measuring and what not due to the location of the mounting holes I can't even fabricate a bracket to mount them so I need to find a set of 18z's. These are undamaged, unpainted and other than dirty in great working condition as I was going to use them myself if it hadn't been for this pesky fitment issue. Anyone out there interested in a trade?
