I don't think I would notice it's gone to be honest! As I have never had it kick in! Just wanderd if the brakes would differ from it not being there! If I'm on track going 120mph into a corner and I pump the brakes I shouldnt have a problem should I? But if I hit them and hope then there's a chance they could lock up and I would have to pump them yeh? The focus rs doesn't have traction control so it's a system only aiding the brakes I would say?
