{"product_id":"supercomp-front-big-brake-kit-356x32mm-8-piston-caliper","title":"Supercomp Front Big Brake Kit 356x32mm 8-Piston Caliper","description":"The Ksport Supercomp Front Big Brake Kit offers a substantial upgrade in stopping power for your BMW E53 X5. The SuperComp calipers are forged from aircraft-quality billet aluminum, featuring a differential bore configuration and larger pistons compared to ProComp calipers, ensuring superior rigidity and pad wear. They weigh just over 7 lbs each and include protection grooves for bridge tubes, 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 the stainless-steel brake lines prevent expansion under pressure. Due to the caliper size, each unit utilizes four brake pads.\n\nThe kit includes a 2-piece floating disc assembly that reduces both rotating and unsprung weight, while also mitigating thermal stresses that can cause warping. The rotors feature a unique slot design to minimize braking noise and expel gas and pad debris more efficiently than conventional designs. These rotors are heat-treated and balanced for optimal performance. Cross-drilled rotors are recommended for daily driven vehicles for cooler operation, while slotted rotors are better suited for track use. Ksport provides standard SC5 Street Pads, designed for optimal performance under street and occasional track conditions with an optimal operating temperature range of 194°F – 1022°F. Alternatively, RC5 Race Pads are available, offering superior stopping power under extreme track conditions with an optimal temperature range of 482°F – 1472°F; these are not recommended for street use. All Ksport Big Brake Kits come with a 12-month limited warranty against manufacturer defects. This product is made to order, and an estimated time of arrival will be provided after the order is submitted to the supplier.","brand":"Ksport","offers":[{"title":"Default Title","offer_id":52868437672248,"sku":"BKBM100-846CO","price":2866.57,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0970\/4895\/3144\/files\/687986992.jpg?v=1787914161","url":"https:\/\/store.motormia.co\/products\/supercomp-front-big-brake-kit-356x32mm-8-piston-caliper","provider":"MOTORMIA","version":"1.0","type":"link"}
