So guys What else will i need for this ?
OK, looking at the fleabay ad, that is a Leon Cupra, not a Leon CupraR, they did 2 models, one with 180BHP the other with 210/225 depending on year of manufacturer. The 312mm setup is basically standard 8L S3 brakes, I think the caliper is the same as your 1.8T ones, just the carriers are bigger so you can fit the bigger disks on. If you paid £200 for the 312mm setup, I personally think you have been fleeced, especially if they didn't supply you with the carriers to make it work!
Just bought some 312mm standard discs and calipers off a Seat Leon Cupra R and was under the impression they would bolt straight on with my 18" rims?
