Narrow Superlite 6R billet calipers run six pistons in 1.62 in, 1.12 in, and 1.12 in bores for 4.04 sq in of piston area, clamping BP-10 pads on 12.88 in by 1.10 in iron rotors with an SRP drilled and slotted face. Disc and hat are cast as one piece over a 32 straight vane core, cutting cost and part count against a separate rotor and aluminum hat, and the rotor bolts to forged aluminum hub 270-13636. Calipers, rotors, hubs, brackets, and hardware are included in black powder coat, and the kit needs a factory drum spindle and a 17 in or larger wheel.
