Semimetallic brake pads offer a pad in between both the sintered and organic brake pads. Perfect choice for polished or chromed rotors and recommended for use with Billet Steel Rotors for best results. All three compounds of Drag Specialties brake pads are asbestos-, nickel-, and lead-free. Sold in pairs. NOTE: If you are using aftermarket billet steel rotors it is recommended you use our Organic-Kevlar brake pads to avoid damage to them. Sintered pads are not recommended for billet steel rotors as the pad material is too aggressive for those rotors.
