Changed pads and discs on a Ford Focus mk3.5 to Borg and beck. The quality of these discs if fantastic. Pads include bonded anti squeal plates and the discs come with a coating preventing rusting. Fitted them and there is no noticeable difference in braking from the original OE ones. They were smooth and braked perfectly from the start. These are top quality components at half the price of OE from a dealer.
