{"product_id":"4-piston-caliper-big-brake-kit-3","title":"4-Piston Caliper Big Brake Kit","description":"Constructed with a focus on durability and weight reduction, the kit features 1-piece billet aluminum calipers with aluminum pistons for excellent heat resistance and corrosion-free operation. The opposed-piston caliper design ensures consistent pad grip and minimizes uneven wear. Reinforced carbon steel caliper brackets allow for direct bolt-on installation to existing mounting points.\n\nThe kit includes 2-piece, vented rotors with drilled surfaces and aluminum centers. This design not only reduces rotational mass for quicker braking response and shorter stopping distances but also helps prevent rotor warpage by allowing for more unrestricted expansion and contraction. Heavy-duty caliper seals are incorporated for sustained high-temperature racetrack use, and stainless steel brake lines contribute to faster pedal response by preventing expansion under pressure.\n\nThe kit is suitable for performance and racing driving styles and requires a minimum wheel diameter of 18 inches (457mm).","brand":"Ksport","offers":[{"title":"Default Title","offer_id":52868704305464,"sku":"BKSB050-443CO","price":2715.69,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0970\/4895\/3144\/files\/687991490.webp?v=1787915882","url":"https:\/\/store.motormia.co\/products\/4-piston-caliper-big-brake-kit-3","provider":"MOTORMIA","version":"1.0","type":"link"}
