You can use your calipers with some spacers with 2wd Cossie discs or sell the lot and fit Focus ST170 discs, calipers. From experience they work a treat and my chosen tuner says I'm a bit of an animal. lol

If you have the ABS system it's worth removing it as it's crap and deadens their feel.

Stick with the Mondeo rims Cossie rims look good but fuck how the car drives.
