MPF1987 "Hi mate,
First off the calipers on the focus RS are the same as on a fiat coupe turbo, seat leon cupra and pug 406 coupe so they could be off any off 4, It doesnt really make a diffrence what they are off as they are a brembo caliper (as you know im not bein funny) that will fit any of the above 4."

Thanks for the comments. I appreciate what you are saying and I am aware that the calipers should fit any of the above, however I bought these in the belief that they were original Focus RS brakes which it seems they are not. Regardless what's done is done but I do feel it was unfair misleading me into believing they were Focus RS brakes.
