{"product_id":"procomp-big-brake-kit-13-inch-rotor","title":"Procomp Big Brake Kit, 13-Inch Rotor","description":"The Ksport Procomp Big Brake Kit is engineered to significantly enhance the stopping power of your BMW 3 Series Wagon F31 (2012-2018). The kit features a lightweight, one-piece caliper CNC machined from aircraft-quality billet aluminum, weighing just over 5 lbs. It incorporates an opposed-piston caliper design for improved pad wear and rigidity over OEM components. Standard features include aluminum caliper pistons, high-temperature seals, and stainless-steel brake pad wear plates.\n\nThe kit utilizes a 2-piece disc assembly to reduce rotating and unsprung weight, with options for a floating disc to prevent warping from thermal stress. The unique slot design on the rotors helps expel gas and pad debris, reducing braking noise. Rotors are heat-treated and balanced for optimal performance. While cross-drilled rotors run cooler, slotted rotors, as featured in this specific kit (BKBM251-433SO), are recommended for vehicles that see more track use. The kit is available in four standard caliper colors, including the featured orange, with over 20,000 custom color options available. Stainless steel brake lines are included to prevent expansion under pressure, ensuring faster pedal response.\n\nThis specific kit (BKBM251-433SO) is designed for the BMW 3 Series Wagon F31 chassis from 2012-2018. It is compatible with both 2WD and 4WD models but specifically excludes the M Package. Ksport offers two pad options: SC5 Street pads for daily driving and RC1 Race Pads for track use. All Ksport big brake kits come with a 12-month warranty covering manufacturer defects.","brand":"Ksport","offers":[{"title":"Default Title","offer_id":52868446060856,"sku":"BKBM251-433SO","price":2293.25,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0970\/4895\/3144\/files\/687986306.webp?v=1787914273","url":"https:\/\/store.motormia.co\/products\/procomp-big-brake-kit-13-inch-rotor","provider":"MOTORMIA","version":"1.0","type":"link"}
