Narrow Superlite 6R billet calipers use 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 Spec-37 iron rotors with a GT 48 curved vane core and an SRP drilled and slotted face. The kit bolts to both standard OEM single piston and 1LE dual piston caliper spindles, and its forged aluminum hub adds 0.25 in of outboard offset on a 5x4.75 bolt circle. Calipers, rotors, hats, hubs, a stainless flexline kit, and hardware ship in red powder coat, and 17 in wheels are the minimum.
