{"product_id":"procomp-8-piston-356mm-front-brake-kit","title":"ProComp 8-Piston 356mm Front Brake Kit","description":"The Ksport Procomp Big Brake Kit offers a substantial upgrade in stopping power, integrating advanced brake technology to significantly reduce brake fade and continually refresh the brake pad surface during operation.\n\nThe kit features extreme lightweight ProComp 8-piston calipers, machined from aircraft-quality billet, which come in a differential bore configuration. These calipers weigh just over 5lbs each and include protection grooves for bridge tubes. Standard features on each caliper include aluminum pistons, high-temperature seals, and stainless steel brake pad wear plates, contributing to improved pad wear and caliper rigidity over OEM designs.\n\nUtilizing a 2-piece floating disc assembly, this kit reduces both rotating and unsprung weight. The floating disc design also mitigates thermal stresses from extreme heat, preventing rotor warping or cupping of the braking surface. The unique slot design on the rotors effectively reduces braking noise and more rapidly expels gas and pad debris compared to conventional slot designs. Each rotor is heat-treated and balanced for optimal performance. This specific kit features slotted rotors, which are recommended for vehicles that see more track use than daily driving.\n\nThis Ksport Procomp Big Brake Kit (BKAU140-841SO) is specifically designed for the 2004-2005 Audi S4 B6 Chassis with the 4.2L V8 engine.","brand":"Ksport","offers":[{"title":"Default Title","offer_id":52868262003000,"sku":"BKAU140-841SO","price":2534.65,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0970\/4895\/3144\/files\/687979711.webp?v=1787913926","url":"https:\/\/store.motormia.co\/products\/procomp-8-piston-356mm-front-brake-kit","provider":"MOTORMIA","version":"1.0","type":"link"}
