{"product_id":"supercomp-8-piston-400mm-slotted-big-brake-kit","title":"Supercomp 8-Piston 400mm Slotted Big Brake Kit","description":"The Ksport Supercomp Big Brake Kit is engineered to provide the ultimate in stopping power for your BMW 3 Series E46 (1999-2005). This advanced braking system integrates new brake technology to drastically reduce brake fade and continually cool the brake pad surface during intense use.\n\nThis kit boasts a 400mm slotted, 2-piece floating rotor assembly, which helps reduce rotating and unsprung weight while preventing thermal stress and warping from extreme heat. The SuperComp caliper is a lightweight, 8-piston unit machined from aircraft-quality billet, featuring a differential bore configuration, larger pistons than the ProComp calipers, aluminum pistons, high-temperature seals, and stainless steel brake pad wear plates. The opposed-piston caliper design significantly improves pad wear and caliper rigidity over OEM setups, while the stainless steel brake lines resist expansion under pressure.\n\nThe unique slot design on the rotor efficiently expels gas and pad debris, reducing braking noise and enhancing performance. This specific kit is recommended for vehicles that will see more track use than daily driving, as slotted rotors are favored for their ability to manage heat and debris in demanding conditions. The kit includes replacement calipers, rotors, pads, brake lines, and all necessary hardware.","brand":"Ksport","offers":[{"title":"Default Title","offer_id":52868430856504,"sku":"BKBM031-961SO","price":4827.9,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0970\/4895\/3144\/files\/687983691.webp?v=1787914080","url":"https:\/\/store.motormia.co\/products\/supercomp-8-piston-400mm-slotted-big-brake-kit","provider":"MOTORMIA","version":"1.0","type":"link"}
