{"product_id":"procomp-380mm-slotted-rear-big-brake-kit","title":"Procomp 380mm Slotted Rear Big Brake Kit","description":"The Ksport Procomp Big Brake Kit offers a significant upgrade in stopping power for your vehicle, specifically designed for the 2001-2006 BMW M3 E46 chassis. It incorporates advanced brake technology to provide a refreshing surface for the brake pads during use.\n\nThe caliper in this kit is the ProComp 6-piston model, finished in a striking red. Constructed from aircraft-quality billet aluminum, it is exceptionally lightweight, weighing just over 5 lbs. Key features include a differential bore configuration, machined protection grooves for bridge tubes, aluminum pistons, high-temperature seals, and stainless steel brake pad wear plates. The opposed piston design enhances pad wear and caliper rigidity compared to OEM components, while the included stainless steel brake lines prevent expansion under pressure.\n\nThis rear kit utilizes a 2-piece floating disc assembly, which helps reduce both rotating and unsprung weight. The floating design also mitigates thermal stress from extreme heat, preventing the disc from warping or the braking surface from becoming cupped. The slotted rotor design is optimized to reduce braking noise and efficiently expel gas and pad debris, making it particularly suitable for track use. Every rotor is heat-treated and balanced for optimal performance. The application is specifically listed for the 2001-2006 BMW M3 E46 Chassis with the 3.2L 3246CC l6 GAS DOHC Naturally Aspirated engine.","brand":"Ksport","offers":[{"title":"Default Title","offer_id":52868432331064,"sku":"BKBM050-653SO","price":4043.37,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0970\/4895\/3144\/files\/687986061.jpg?v=1787914097","url":"https:\/\/store.motormia.co\/products\/procomp-380mm-slotted-rear-big-brake-kit","provider":"MOTORMIA","version":"1.0","type":"link"}
