{"product_id":"supercomp-rear-big-brake-kit-356mm-1","title":"Supercomp Rear Big Brake Kit 356mm","description":"The Ksport Supercomp Rear Big Brake Kit offers enhanced stopping power for your BMW E84 X1. The SuperComp caliper, forged from aircraft-quality billet aluminum, features a differential bore configuration with larger pistons than standard ProComp calipers. It weighs just over 7 lbs and includes protection grooves for bridge tubes, aluminum pistons, high-temperature seals, titanium brake pad retainer clips, and stainless-steel wear plates. The opposed piston caliper design improves pad wear and caliper rigidity, while stainless-steel brake lines prevent expansion under pressure. Each caliper requires four brake pads due to its substantial size.\n\nThe kit includes a 2-piece floating disc assembly, which reduces both rotating and unsprung weight and prevents thermal stress from warping the disc. The unique slot design on the rotor minimizes braking noise and efficiently expels gas and pad debris. Rotors are heat-treated and balanced for optimal performance. Cross-drilled rotors are recommended for daily-driven vehicles as they tend to run cooler, while slotted rotors are better suited for track use. Standard equipment includes Ksport SC5 Street Pads, designed for optimal braking under street and occasional track conditions, offering reduced dust and noise. Optional Ksport RC5 Race Pads, made from carbon metallic, are available for extreme track conditions but are not recommended for street use due to their high operating temperature requirement.\n\nThis kit is specifically designed for the BMW X1 E84 models from 2012-2015, compatible with the sDrive28i N20 2.0L, xDrive28i N20 2.0L, and xDrive35i N55 3.0L engines. It is important to note that this product is made to order and is non-refundable once the order is placed.","brand":"Ksport","offers":[{"title":"Default Title","offer_id":52868449665336,"sku":"BKBM340-447CO","price":2770.56,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0970\/4895\/3144\/files\/687985591.jpg?v=1787914326","url":"https:\/\/store.motormia.co\/products\/supercomp-rear-big-brake-kit-356mm-1","provider":"MOTORMIA","version":"1.0","type":"link"}
