{"product_id":"supercomp-8-piston-rear-big-brake-kit-400mm","title":"Supercomp 8 Piston Rear Big Brake Kit 400mm","description":"The Ksport Supercomp Big Brake Kit represents the pinnacle of braking upgrades, engineered to deliver exceptional stopping power for your Mazda RX-7 FC3S (1986-1991) without requiring any modifications to your vehicle's original setup. This sophisticated bolt-on system builds upon the Procomp kit's capabilities with larger calipers, rotors, and brake pads, enhanced with more pistons and standard full-floating rotors for improved self-centering and reduced drag.\n\nThe calipers are precision-machined from a solid billet of aircraft-grade aluminum, ensuring a lightweight yet incredibly strong and corrosion-free component. They feature aluminum pistons for superior heat resistance and reliability. Complementing the calipers are CNC-machined carbon steel brackets that allow for a direct bolt-on installation to the OEM caliper mounting locations. The kit includes 400mm diameter, 36mm wide, two-piece floating rotors, available in either cross-drilled or slotted options, with cross-drilled recommended for daily driving and slotted for track use.\n\nIncluded in the kit are Ksport's SC5 Street Brake Pads, designed for optimal performance in street and occasional track conditions, offering reduced dust and noise. The system also features D.O.T. compliant stainless-steel braided brake lines, which prevent expansion under pressure, leading to a quicker pedal response and a firmer pedal feel compared to standard rubber lines.\n\nStandard kit contents include: (2) Forged, Monoblock Aluminum Calipers, (2) Lightweight Two-Piece Rotors (Slotted or Drilled), (1) Set of SC5 Street Brake Pads, (2) Stainless Steel Brake Lines, all required mounting components and hardware, and an Owner's Manual. Please note that Ksport Big Brake kits are built to order, and production\/delivery typically takes 4-6 weeks. The product also comes with a Proposition 65 warning regarding cancer and reproductive harm.","brand":"Ksport","offers":[{"title":"Default Title","offer_id":52868612358456,"sku":"BKMZ140-862CO","price":4169.55,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0970\/4895\/3144\/files\/687993203.webp?v=1787915519","url":"https:\/\/store.motormia.co\/products\/supercomp-8-piston-rear-big-brake-kit-400mm","provider":"MOTORMIA","version":"1.0","type":"link"}
