{"product_id":"wilwood-140-16017","title":"Wilwood Rear Superlite 4R\/ST Road Race Brake Kit for BMW M3 (1995–1999), 13-Inch GT Rotors and Parking Brake Delete","description":"\u003cp\u003eThis rear Superlite 4R\/ST race conversion removes the parking-brake hardware and replaces the service brake with four-piston calipers and dynamically mounted 13-inch GT rotor rings. The configuration is specific to the documented BMW M3 rear upright and hub, with braided flexlines included. Wilwood Engineering, founded by Bill Wood in 1977, designs and manufactures disc brake systems from Camarillo, California. Its motorsport, street-performance and specialized product range spans calipers, brake rotors, master cylinders, valves, fittings and brake lines. A conversion must be considered as a complete brake system when selecting those parts.\u003c\/p\u003e\u003ch3\u003eTechnical Details\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003eManufacturer part number: 140-16017; supplied as one rear axle brake kit.\u003c\/li\u003e\n\u003cli\u003eRotor dimensions: 13.00 in; 330.2 mm outside diameter; 1.00 in; 25.4 mm thick.\u003c\/li\u003e\n\u003cli\u003eSupplied service pads: BP-35 compound; verify suitability for the intended operating conditions.\u003c\/li\u003e\n\u003cli\u003eMechanical contents: Separate wheel hubs are not included; mounting hardware supplied; spindles not included.\u003c\/li\u003e\n\u003cli\u003eHydraulic installation: Braided flexlines are included; master cylinder not included; brake booster not included.\u003c\/li\u003e\n\u003cli\u003eCaliper finish and port: Type III Anodize; hydraulic inlet 1\/8-27 NPT.\u003c\/li\u003e\n\u003cli\u003eCataloged rotor\/hat mounting-hole pattern: 5 x 4.75 in; 5 x 120.65 mm bolt circle; cataloged stud-hole clearances 0.610 in; 15.49 mm.

Review DS1391 for rear-upright preparation, 1.080-inch hat positioning and hub-register checks; it does not retain a parking-brake function. Confirm the front-to-rear hydraulic balance and the full 17-inch wheel-clearance drawing. BP-35 competition pads require heat and can produce accelerated wear in prolonged low-temperature service.\u003c\/p\u003e\u003cp\u003eUse the fitment table below to confirm each model, year, trim and brake-package condition.
