{"product_id":"procomp-6-piston-rear-big-brake-kit-6","title":"Procomp 6-Piston Rear Big Brake Kit","description":"The Ksport Procomp Big Brake Kit is engineered to provide superior stopping power for your 1986-1991 Mazda RX-7 FC3S chassis. This rear brake system integrates advanced technology to drastically reduce brake fade and continuously cool the brake pads during use, ensuring consistent performance even under demanding conditions.\n\nThis kit includes a lightweight, 6-piston ProComp caliper machined from aircraft-quality billet, weighing just over 5 lbs each. The caliper features differential bore configurations, protection grooves for bridge tubes, aluminum pistons, high-temperature seals, and stainless steel wear plates. The opposed piston design enhances pad wear and caliper rigidity compared to OEM systems, while the included stainless steel brake lines prevent expansion under pressure. The 2-piece floating disc assembly reduces rotational and unsprung weight and minimizes thermal stress to prevent rotor warping. The unique slot design on the rotors helps reduce braking noise and efficiently expels gas and debris, making it ideal for track use.\n\nThe kit utilizes 380mm (15-inch) slotted rotors for optimal performance in track environments. Please note that the OEM handbrake will not function with this big brake kit installed.","brand":"Ksport","offers":[{"title":"Default Title","offer_id":52868612391224,"sku":"BKMZ140-652SO","price":3511.2,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0970\/4895\/3144\/files\/687992458.jpg?v=1787915522","url":"https:\/\/store.motormia.co\/products\/procomp-6-piston-rear-big-brake-kit-6","provider":"MOTORMIA","version":"1.0","type":"link"}
