{"product_id":"supercomp-rear-big-brake-kit-21","title":"Supercomp Rear Big Brake Kit","description":"The Ksport Supercomp Rear Big Brake Kit is engineered to deliver ultimate stopping power for your BMW E46 M3. This advanced braking system integrates new technology to significantly reduce brake fade and continuously cool the brake pads during operation.\n\nThe SuperComp caliper is a standout feature, crafted from aircraft-quality billet aluminum. It boasts a differential bore configuration with larger pistons compared to Ksport's ProComp calipers, weighing just over 7 lbs each. Standard features include aluminum pistons, 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 in the SuperComp series utilizes four brake pads.\n\nThis kit includes a 2-piece floating disc assembly, which reduces both rotating and unsprung weight. The floating disc design also mitigates thermal stresses that can cause warping or cupping of the braking surface under extreme heat. Ksport offers rotors in both cross-drilled and slotted designs. Cross-drilled rotors are recommended for daily driven vehicles as they tend to run cooler, while slotted rotors are better suited for track use. This specific kit includes 356mm x 32mm cross-drilled rotors.\n\nOptional upgrades include Ksport SC5 Street Pads, which are designed for optimal street and occasional track performance, and Ksport RC5 Race Pads, made from carbon metallic for extreme track conditions. The kit is made to order, with estimated delivery times provided after order submission. Customization options for caliper color and brake pad types are available.","brand":"Ksport","offers":[{"title":"Default Title","offer_id":52868432298296,"sku":"BKBM050-447CO","price":2770.56,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0970\/4895\/3144\/files\/687986902.jpg?v=1787914096","url":"https:\/\/store.motormia.co\/products\/supercomp-rear-big-brake-kit-21","provider":"MOTORMIA","version":"1.0","type":"link"}
