{"product_id":"8-piston-billet-aluminum-big-brake-kit-3","title":"8-Piston Billet Aluminum Big Brake Kit","description":"The Ksport SuperComp Big Brake Kit is K-Sport's most extreme brake upgrade, engineered to deliver the highest level of stopping power with larger-diameter disc rotors and an 8-piston caliper design.\n\nConstructed for durability and performance, the calipers feature a 1-piece billet aircraft-grade aluminum body for light weight and exceptional strength, while aluminum pistons resist corrosion and improve heat management. The 2-piece vented rotors, made from cast iron with an aluminum center, reduce rotational mass, enhance braking response, and shorten stopping distances. The 2-piece design also minimizes rotor warpage by allowing for more natural expansion and contraction.\n\nThe kit includes reinforced carbon steel caliper brackets that allow these larger-than-OEM calipers to mount directly to existing points. For sustained high-temperature use, all caliper seals are heavy-duty, and stainless steel brake lines are included to prevent expansion under pressure, ensuring faster pedal response.\n\nThis big brake kit requires a minimum wheel diameter of 18 inches (457mm) and features 14-inch (356mm) drilled rotors. The kit is specifically designed for the 2005-2007 Subaru Impreza STI.","brand":"Ksport","offers":[{"title":"Default Title","offer_id":52868719280440,"sku":"BKSB120-846CO","price":2605.97,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0970\/4895\/3144\/files\/687992976.webp?v=1787915951","url":"https:\/\/store.motormia.co\/products\/8-piston-billet-aluminum-big-brake-kit-3","provider":"MOTORMIA","version":"1.0","type":"link"}
