{"product_id":"supercomp-8-piston-front-big-brake-kit-8","title":"Supercomp 8-Piston Front Big Brake Kit","description":"The Ksport SuperComp Big Brake Kit is engineered to deliver ultimate stopping power for your BMW F31 3-Series Wagon. This front brake system utilizes an extreme lightweight SuperComp caliper, forged from aircraft quality billet aluminum. The caliper features a differential bore configuration with significantly larger pistons than standard, offering enhanced rigidity and improved pad wear over OEM designs. It incorporates aluminum pistons, high-temperature seals, titanium brake pad retainer clips, and stainless-steel brake pad wear plates.\n\nThis kit includes a 2-piece floating disc assembly with 356mm (14-inch) cross-drilled rotors, which reduce rotating and unsprung weight while preventing thermal stress warping. The unique slot design on the rotor helps expel gas and pad debris efficiently. Cross-drilled rotors are recommended for daily driven vehicles as they tend to run cooler. Stainless steel brake lines are standard, improving pedal feel and response by eliminating expansion under pressure.\n\nThe SuperComp kit comes standard with Ksport SC5 Street Pads, designed for optimal performance in street and occasional track conditions. These ceramic pads offer reduced brake dust and noise compared to race pads. Optional Ksport RC5 Race Pads, made from carbon metallic, are available for extreme track use but are not recommended for street driving due to their high working temperature.\n\nCaliper brackets are CNC machined from carbon steel to bolt directly to the OEM caliper location. This kit is made to order and is non-refundable. It comes with a 12-month limited warranty against manufacturer defects.","brand":"Ksport","offers":[{"title":"Default Title","offer_id":52868446355768,"sku":"BKBM251-846CO","price":2866.57,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0970\/4895\/3144\/files\/687986307.webp?v=1787914278","url":"https:\/\/store.motormia.co\/products\/supercomp-8-piston-front-big-brake-kit-8","provider":"MOTORMIA","version":"1.0","type":"link"}
