{"product_id":"procomp-rear-big-brake-kit-8","title":"Procomp Rear Big Brake Kit","description":"The Ksport Procomp BMW 6 Series Rear Big Brake Kit is a sophisticated, bolt-on upgrade engineered to deliver superior stopping power, especially under high-heat conditions. Each caliper is constructed from a solid billet of aircraft-grade aluminum in a one-piece design, ensuring lightweight strength and resistance to corrosion. Aluminum pistons are incorporated for enhanced heat management, while opposed-piston designs promote consistent brake pad wear and grip. High-temperature seals, titanium brake pad retainer clips, and stainless-steel pad wear plates are standard features.\n\nThe two-piece design allows the outer rotor to expand and contract independently, reducing warping, and the aluminum center acts as a heat sink. Buyers can choose between cross-drilled rotors, recommended for daily driven vehicles due to cooler operation, or slotted rotors, ideal for track use, which help dissipate heat and wipe away gases and debris.\n\nStandard inclusions for the kit are two forged, monoblock aluminum calipers, two lightweight two-piece rotors (slotted or drilled), a set of SC5 Street Brake Pads, two stainless steel brake lines, and all necessary mounting components and hardware. The SC5 pads offer optimal street and occasional track performance with reduced dust and noise. Ksport offers an optional upgrade to RCI Race Pads for extreme track conditions.\n\nThe system is compatible with 19-inch wheels and larger. Important note: Ksport Big Brake kits are built to order, requiring an estimated 4-6 weeks for production and delivery.","brand":"Ksport","offers":[{"title":"Default Title","offer_id":52868441702712,"sku":"BKBM150-653SO","price":4043.37,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0970\/4895\/3144\/files\/687984692.webp?v=1787914214","url":"https:\/\/store.motormia.co\/products\/procomp-rear-big-brake-kit-8","provider":"MOTORMIA","version":"1.0","type":"link"}
