{"product_id":"procomp-supercomp-8-piston-rear-big-brake-kit","title":"Procomp SuperComp 8-Piston Rear Big Brake Kit","description":"The Ksport Procomp Big Brake Kit is engineered to deliver superior stopping power and performance for your vehicle, specifically designed for the 1988-1991 BMW M3 E30 Chassis. This rear brake upgrade system integrates advanced brake technology to significantly reduce brake fade and continuously cool the brake pads.\n\nThe kit includes a lightweight, red SuperComp 8-piston caliper, machined from aircraft quality billet and weighing just over 5lbs. It features a differential bore configuration, machined protection grooves, aluminum pistons, high-temperature seals, and stainless steel wear plates. The opposed piston design enhances pad wear and caliper rigidity over OEM systems. The included stainless steel brake lines prevent expansion under pressure, ensuring consistent braking feel.\n\nThis kit utilizes a 2-piece floating disc assembly with a 400mm slotted rotor. This design reduces rotating and unsprung weight, while the floating assembly mitigates thermal stress and prevents warping. Slotted rotors are recommended for vehicles that see more track use than daily driving, offering improved performance under demanding conditions.","brand":"Ksport","offers":[{"title":"Default Title","offer_id":52868428497208,"sku":"BKBM011-863SO","price":4767.55,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0970\/4895\/3144\/files\/687983647.jpg?v=1787914050","url":"https:\/\/store.motormia.co\/products\/procomp-supercomp-8-piston-rear-big-brake-kit","provider":"MOTORMIA","version":"1.0","type":"link"}
