{"product_id":"dualcomp-rear-big-brake-kit-25","title":"Dualcomp Rear Big Brake Kit","description":"The Ksport Dualcomp Rear Big Brake Kit offers an advanced braking solution for the BMW E8X 1M Coupe, specifically engineered with drifting and rally racing in mind. This unique Dualcomp system utilizes a single 4-piston caliper, with two pistons dedicated to the primary foot brake and the other two independently managing the handbrake function.\n\nConstructed with a lightweight, forged one-piece caliper from aerospace-quality aluminum, this kit is built for extreme durability and resistance to fracturing, warpage, and failure. The opposed-piston design guarantees consistent pad grip and wear. Standard features include high-temperature seals, titanium brake pad retainer clips, and stainless-steel wear plates.\n\nThe 6061-T6 aircraft-grade aluminum center sections minimize rotational mass for quicker stopping and improved brake response. This two-piece design also allows the rotor to expand and contract independently, reducing the likelihood of warping due to heat buildup, and the aluminum center acts as a heat sink. For daily driven vehicles, cross-drilled rotors are recommended as they run cooler. Slotted rotors are available for vehicles with more track use.\n\nThis Big Brake Kit is Formula Drift legal and comes standard with SC5 Street Pads, offering optimal braking performance for street and occasional track use with reduced dust and noise. An upgrade to RCI Race Pads is available for extreme track conditions. The kit also features CNC machined carbon steel caliper brackets for direct bolt-on installation to OEM locations, D.O.T. compliant stainless-steel braided brake lines for improved pedal response and feel, and a polished Titanium handbrake cylinder and lever. Caliper color, rotor style, and center bell upgrades are customizable. This product is made to order and is non-refundable.","brand":"Ksport","offers":[{"title":"Default Title","offer_id":52868440391992,"sku":"BKBM135-445CO","price":3439.88,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0970\/4895\/3144\/files\/687986198.jpg?v=1787914197","url":"https:\/\/store.motormia.co\/products\/dualcomp-rear-big-brake-kit-25","provider":"MOTORMIA","version":"1.0","type":"link"}
