Four-piston Superlite 4R calipers and 12.88-inch rotors use parking-brake hats designed around the existing BMW mechanism. From its Camarillo, California base, Wilwood Engineering designs disc brake systems for motorsport, street-performance and specialized needs. Founded in 1977 by Bill Wood, its range covers calipers, rotors, master cylinders, valves, fittings and brake lines chosen to work within a complete brake system.\u003c\/p\u003e\u003ch3\u003eTechnical Details\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003eManufacturer part number: 140-14752-D.\u003c\/li\u003e\n\u003cli\u003eMatch the Superlite 4R caliper architecture when selecting related components: radial attachment, 4 stainless pistons, forged aluminum body and Black Powder Coat finish.\u003c\/li\u003e\n\u003cli\u003ePad selection is BP-10; piston-bore measurements are 1.25, 1.25 inches.
