{"product_id":"supercomp-rear-big-brake-kit-26","title":"Supercomp Rear Big Brake Kit","description":"The Ksport Supercomp Rear Big Brake Kit is engineered to deliver the ultimate stopping power for your BMW E90, E91, or E92 3-Series vehicle. This comprehensive system integrates advanced brake technology to significantly reduce brake fade and ensure consistent cooling of the brake pads under demanding conditions. The SuperComp caliper, forged from aircraft-quality billet aluminum, is extremely lightweight (just over 7 lbs.) and features a differential bore configuration with larger pistons than Ksport's ProComp calipers, enhancing braking performance and caliper rigidity. Aluminum pistons, high-temperature seals, titanium brake pad retainer clips, and stainless-steel wear plates are standard, complemented by stainless-steel brake lines that resist expansion under pressure.\n\nEach kit features a 2-piece floating disc assembly designed to minimize both rotating and unsprung weight. This floating design also combats thermal stresses, preventing disc warping and surface cupping during extreme heat. The unique slot design on the rotors aids in reducing braking noise and efficiently expels gas and pad debris. Ksport offers rotors in both cross-drilled (recommended for daily driving due to cooler operation) and slotted (recommended for track use) configurations. Standard equipment includes Ksport SC5 Street Pads, formulated with NAOC ceramic for optimal street and occasional track performance, with an optional upgrade to RC5 Race Pads, which are carbon-metallic and designed for extreme track conditions.\n\nThe kit includes custom-engineered, CNC-machined carbon steel caliper brackets that allow the larger Ksport calipers to bolt directly onto the OEM caliper locations. All Ksport big brake kits come with a 12-month limited warranty covering manufacturer defects. Please note that this product is made to order and is non-refundable or exchangeable once the order is placed.","brand":"Ksport","offers":[{"title":"Default Title","offer_id":52868436853048,"sku":"BKBM091-863CO","price":4334.14,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0970\/4895\/3144\/files\/687983783.jpg?v=1787914148","url":"https:\/\/store.motormia.co\/products\/supercomp-rear-big-brake-kit-26","provider":"MOTORMIA","version":"1.0","type":"link"}
