{"product_id":"supercomp-rear-big-brake-kit-28","title":"Supercomp Rear Big Brake Kit","description":"The Ksport Supercomp Rear Big Brake Kit is engineered to deliver the ultimate in stopping power for your BMW E60\/E61 M5. This advanced braking system integrates cutting-edge technology to drastically reduce brake fade and ensure consistent cooling and refreshing of the brake pad surface, even under demanding conditions.\n\nThe SuperComp caliper is an extreme lightweight, forged from aircraft-quality billet aluminum, weighing just over 7 lbs. It features a differential bore configuration with larger pistons than ProComp calipers, along with protection grooves, high-temperature seals, titanium brake pad retainer clips, and stainless-steel brake pad wear plates. The opposed piston design enhances pad wear and caliper rigidity, while stainless-steel brake lines prevent expansion under pressure. Each caliper utilizes four brake pads due to its substantial size.\n\nThis kit includes a 2-piece floating disc assembly, which reduces rotating and unsprung weight. The floating disc design mitigates thermal stress from extreme heat, preventing warping and cupping. The unique slot design on the rotor minimizes braking noise and efficiently expels gas and pad debris. Cross-drilled rotors are standard and recommended for daily driven vehicles, running cooler than slotted options. This kit comes standard with Ksport SC5 Street Pads, which are ceramic and designed for optimal performance in street and occasional track conditions, reducing dust by over 50% compared to race pads. An optional upgrade to Ksport RC5 Race Pads (carbon metallic) is available for extreme track use, though not recommended for street driving due to higher operating temperatures.","brand":"Ksport","offers":[{"title":"Default Title","offer_id":52868438622520,"sku":"BKBM111-437CO","price":2625.17,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0970\/4895\/3144\/files\/687983812.jpg?v=1787914171","url":"https:\/\/store.motormia.co\/products\/supercomp-rear-big-brake-kit-28","provider":"MOTORMIA","version":"1.0","type":"link"}
