Just been looking at official Ford Focus RS MK2 launch videos on Ford website. On there Jos Capito is telling us how great the front brakes are on the new FOCUS RS MK2. Apparently the calipers are an upgrade compared to the focus st caliper. I have looked at my mates Rs Focus mk2 and they are indeed a different caliper to my ST calipers. My mate reckons the brakes on the RS are excellent. I wondered if anyone had looked into fitting the RS caliper and disc as an upgrade, obviously these would have to be with 19 inch wheels i reckon, wonder if they would fit the ST? due to the RS being revoknuckle so the hub mounting may be different! - mmm! food for thought tho!
