{"product_id":"supercomp-rear-big-brake-kit-400x36mm","title":"Supercomp Rear Big Brake Kit 400x36mm","description":"The Ksport Supercomp Rear Big Brake Kit is engineered to deliver the ultimate in stopping power for your BMW E92 M3. This advanced braking system integrates new technology to significantly reduce brake fade and continuously cool and refresh the brake pad surface during operation.\n\nThe SuperComp caliper is a standout component, forged from aircraft-quality billet aluminum. It features a differential bore configuration with larger pistons than Ksport's ProComp calipers, weighing just over 7lbs 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 over OEM systems, while stainless steel brake lines prevent expansion under pressure. Due to the caliper's size, each unit utilizes four brake pads.\n\nThis kit includes a 2-piece floating disc assembly, which reduces both rotating and unsprung weight. The floating design mitigates thermal stresses caused by extreme heat, preventing disc warping or cupping. The unique slot design on the rotor reduces braking noise and efficiently expels gas and pad debris. Rotors are heat-treated and balanced for optimal performance. Cross-drilled rotors are recommended for daily-driven vehicles as they tend to run cooler, while slotted rotors are better suited for track use. Standard equipment includes Ksport SC5 Street Pads, made with NAOC ceramic material for optimal performance under street and occasional track conditions. An optional upgrade to Ksport RC5 Race Pads, made from carbon metallic material, is available for extreme track use.\n\nKSport Big Brake Kits are made-to-order and are non-refundable. They come with a 12-month limited warranty covering manufacturer defects. This specific kit is designed for the BMW 3 Series E9X (2006-2012) M3 with the S65 4.0L engine.","brand":"Ksport","offers":[{"title":"Default Title","offer_id":52868437115192,"sku":"BKBM092-863CO","price":4767.55,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0970\/4895\/3144\/files\/687986136.jpg?v=1787914150","url":"https:\/\/store.motormia.co\/products\/supercomp-rear-big-brake-kit-400x36mm","provider":"MOTORMIA","version":"1.0","type":"link"}
