{"product_id":"wilwood-140-15345","title":"Wilwood Rear Inboard Sprint Brake Kit with 11.75-Inch Vented Super Alloy Rotor","description":"\u003cp\u003eBuild a race-only inboard sprint brake around the 11.75-inch vented Super Alloy rotor and four-piston caliper. Check the splined axle interface. Disc brake system design and manufacturing are Wilwood Engineering’s focus. Bill Wood founded the Camarillo, California company in 1977; its range spans brake rotors, master cylinders, calipers, fittings, valves and brake lines for motorsport, specialized and street-performance applications. The choice of individual components depends on the complete brake system.\u003c\/p\u003e\u003ch3\u003eTechnical Details\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003eManufacturer: Wilwood\u003c\/li\u003e\n\u003cli\u003eManufacturer part number: 140-15345\u003c\/li\u003e\n\u003cli\u003eKit classification: Rear Brake Kits - Race\u003c\/li\u003e\n\u003cli\u003eAxle position: Rear Kits\u003c\/li\u003e\n\u003cli\u003eBrake Type: Disc\u003c\/li\u003e\n\u003cli\u003eSelling unit: Sold as a kit.\u003c\/li\u003e\n\u003cli\u003eRecommended Use: Race Only.

It requires a 3.00-inch, 46-spline quick-change axle and the standard inboard side-bell mounting arrangement with 3.50-inch bolt centers. The scalloped 11.75 × 0.81-inch Super Alloy rotor uses a floating adapter and split axle clamp; that clamp is not a wheel hub. Align and secure the clamp within the rotor adapter as DS-1277 directs. The narrow four-piston caliper uses BP-28 race pads and a 1\/8-27 NPT hydraulic inlet. Hoses, a master cylinder and a booster are not included. Race only; not for street use.\u003c\/p\u003e\u003cp\u003e\u003ca href=\"https:\/\/www.wilwood.com\/BrakeKits\/BrakeKitsProdRear?itemno=140-15345\"\u003eWilwood product specifications\u003c\/a\u003e · \u003ca href=\"https:\/\/www.wilwood.com\/PDF\/DataSheets\/ds1277.pdf\"\u003eInstallation instructions\u003c\/a\u003e\u003c\/p\u003e\u003cp\u003eWith more than 20 years of parts and fitment experience, PMB Performance can help compare the existing brake assembly with the required component.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eManufacturer warning — brake pads only:\u003c\/strong\u003e WARNING: Cancer and Reproductive Harm. \u003ca href=\"https:\/\/www.P65Warnings.ca.gov\"\u003ewww.P65Warnings.ca.gov\u003c\/a\u003e.\u003c\/p\u003e","brand":"Wilwood","offers":[{"title":"Default Title","offer_id":67757026115762,"sku":"140-15345","price":815.39,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0521\/8792\/2610\/files\/140-15345_kit-xl.jpg?v=1792443237","url":"https:\/\/pmbperformance.com\/products\/wilwood-140-15345","provider":"PMB Performance","version":"1.0","type":"link"}
