{"product_id":"wilwood-140-14879","title":"Wilwood Rear Superlite 4R Road-Race Brake Kit for Chevrolet Corvette C4 (1988–1996), Anodized Calipers and 12.88-Inch GT Rotors, Deletes Parking Brake","description":"\u003cp\u003eThis dedicated C4 rear race conversion replaces the original combination calipers with anodized four-piston Superlite 4R calipers and 12.88-inch GT rotors. It eliminates the parking brake and uses high-temperature BP-35 pads for sustained racing operation. Founded in 1977 by Bill Wood, Wilwood Engineering is now based in Camarillo, California, where its work centers on disc brake systems and components. Calipers, brake rotors, master cylinders, valves, fittings and brake lines serve motorsport, street-performance and specialized installations; selecting these parts requires considering the complete braking system.\u003c\/p\u003e\u003ch3\u003eTechnical Details\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003eManufacturer part number: 140-14879.\u003c\/li\u003e\n\u003cli\u003eRotor dimensions: outside diameter 12.88 in; 327.15 mm; thickness 1.10 in; 27.94 mm.\u003c\/li\u003e\n\u003cli\u003eService caliper assembly: Superlite 4R; 4 pistons in each caliper; Stainless pistons; Forged Aluminium body; Radial mounting.\u003c\/li\u003e\n\u003cli\u003eSupplied pad compound: BP-35.\u003c\/li\u003e\n\u003cli\u003eHat wheel-stud clearance diameter: 0.560 in; 14.22 mm; 0.520 in; 13.21 mm.\u003c\/li\u003e\n\u003cli\u003eRotor mounting hat: aluminum; Black E-Coat; hat offset 0.880 in.\u003c\/li\u003e\n\u003cli\u003eMechanical package contents: no separate hubs included; mounting hardware included: Yes; spindles included: No.\u003c\/li\u003e\n\u003cli\u003eFlexline specification: Line kit included (manufacturer): None; Rear line-kit reference: 220-8177.\u003c\/li\u003e\n\u003cli\u003eParking-brake provision: the original parking brake is eliminated; no mechanical parking function is supplied.\u003c\/li\u003e\n\u003cli\u003eBrake function and supply: Rear road-race brake kit; Disc braking; rear axle; Sold as a kit.\u003c\/li\u003e\n\u003cli\u003eRotor construction and friction surface: Spec-37 Iron; Vented; GT Slotted; surface finish: Plain.\u003c\/li\u003e\n\u003cli\u003eCaliper color, finish and hydraulic inlet: Anodize; Type III Anodize; inlet 1\/8-27 NPT.\u003c\/li\u003e\n\u003cli\u003eWheel bolt circle: 5 x 4.5 in; 5 x 114.3 mm; 5 x 4.75 in; 5 x 120.65 mm.\u003c\/li\u003e\n\u003cli\u003eNominal minimum wheel diameter: 17 in; 431.8 mm; verify full spoke and barrel clearance using the kit drawing.\u003c\/li\u003e\n\u003cli\u003eRear flange interface: OEM; axle\/flange offset 0.00 in; 0 mm (distinct from rotor-hat offset).\u003c\/li\u003e\n\u003cli\u003eHydraulic package contents: brake lines included: No; master cylinder included: No; booster included: No.\u003c\/li\u003e\n\u003cli\u003eRace pad operating range: BP-35 pads are intended for high-temperature racing; extended low-temperature operation causes premature pad and rotor wear.\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eFitment \u0026amp; Compatibility\u003c\/h3\u003e\u003cp\u003eConfirm the 1988–1996 Corvette rear suspension and OE hub interface.
