{"product_id":"400mm-slotted-rotor-with-8-piston-supercomp-caliper","title":"400mm Slotted Rotor with 8-Piston SuperComp Caliper","description":"The kit integrates new brake technology for enhanced performance. The extreme lightweight SuperComp caliper is machined from aircraft quality billet and features larger pistons than their ProComp calipers, weighing just over 7lbs. It includes aluminum pistons, high-temperature seals, and stainless steel brake pad wear plates, with machined protection grooves for bridge tubes.\n\nThis system utilizes a 2-piece floating disc assembly, which reduces both rotating and unsprung weight. The floating design also prevents thermal stresses from warping the disc or cupping the braking surface. The unique slot design on the 400mm rotor helps reduce braking noise and efficiently expels gas and pad debris. Rotors are heat-treated and balanced for optimal performance. Slotted rotors, like those in this kit, are recommended for vehicles that see more track use than daily driving.\n\nThe opposed piston caliper design enhances pad wear and caliper rigidity compared to OEM designs. Stainless steel brake lines are included to prevent expansion under pressure, ensuring consistent braking performance. This kit is specifically designed for the BMW 5 Series E28 models from 1982-1988, including the 524td, 528e, 533i, and 535i.","brand":"Ksport","offers":[{"title":"Default Title","offer_id":52868442521912,"sku":"BKBM180-961SO","price":4169.55,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0970\/4895\/3144\/files\/687987067.webp?v=1787914226","url":"https:\/\/store.motormia.co\/products\/400mm-slotted-rotor-with-8-piston-supercomp-caliper","provider":"MOTORMIA","version":"1.0","type":"link"}
