OEM and some OE brake pads require minor modification to clear the hat hardware of these rotors. This is necessary to retain the OEM parking brake while accommodating the hardware of GiroDiscs two-piece rotors. The modification involves grinding the backing plate of the pad to match the arc of the pad material. Detailed instructions and a disclaimer are included with purchase.
