{"product_id":"supercomp-8-piston-big-brake-kit-w-421mm-slotted-rotors","title":"SuperComp 8 Piston Big Brake Kit w\/ 421mm Slotted Rotors","description":"This extreme brake upgrade system integrates advanced brake technology to significantly reduce brake fade and maintain optimal brake pad performance through continuous cooling and surface refreshment.\n\nThe SuperComp caliper, crafted from aircraft-quality billet, is exceptionally lightweight and features a differential bore configuration. It weighs just over 5 lbs. and includes protection grooves for bridge tubes. Standard features on each caliper include aluminum pistons, high-temperature seals, and stainless steel brake pad wear plates. The opposed piston design enhances pad wear and caliper rigidity compared to OEM components, while stainless steel brake lines prevent expansion under pressure.\n\nThis kit utilizes a 2-piece floating disc assembly, which minimizes both rotating and unsprung weight. The floating design also mitigates thermal stresses from extreme heat, preventing rotor warping or cupping. The unique slot design on the rotor efficiently expels gas and pad debris, reducing noise and enhancing performance. Rotors are heat-treated and balanced for optimal performance, with slotted rotors recommended for track use.\n\nThis specific kit (BKAU400-971SO) is designed for the 2016-2017 Audi A4 B9 Chassis FWD models with the 2.0L Turbocharged engine.","brand":"Ksport","offers":[{"title":"Default Title","offer_id":52868426105144,"sku":"BKAU400-971SO","price":5793.48,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0970\/4895\/3144\/files\/687984411.jpg?v=1787914016","url":"https:\/\/store.motormia.co\/products\/supercomp-8-piston-big-brake-kit-w-421mm-slotted-rotors","provider":"MOTORMIA","version":"1.0","type":"link"}
