Interestingly, I have a pair of Brembo's from a Rangerover Sport for sale that will make Focus RS calipers look like toys in the size department

Flavour we use in the kits is brand new O/E Porsche, Evo FQ, Ferrari or indeed the R Rover Sport Paul as its all the same across some of the models. And yep next to a FRS caliper they are night and day different in size. No point messing with second hand stuff when new ones are almost as cheap
