Forged Narrow Superlite 4R calipers run two 1.38 in stainless pistons per side for 3.00 sq in of piston area, clamping BP-10 pads on 14.00 in by 1.10 in Spec-37 iron rotors with a GT 72 curved vane core. An SRP drilled and slotted face vents gas and pad dust from the contact patch. A cast iron parking brake hat keeps the OE parking brake, master cylinder output, and ABS working. Calipers, rotors, hats, brackets, and hardware ship in the box with calipers in black powder coat, and an 18 in or larger wheel is required.
