{"product_id":"4-piston-caliper-front-big-brake-kit-with-slotted-rotors","title":"4-Piston Caliper Front Big Brake Kit with Slotted Rotors","description":"The kit includes a lightweight, 4-piston caliper crafted from aircraft-quality billet, featuring differential bore configuration, aluminum pistons, high-temperature seals, and stainless steel brake pad wear plates. Its opposed piston design enhances caliper rigidity and pad wear compared to OEM systems, and the included stainless steel brake lines are built to withstand pressure without expanding.\n\nThe kit utilizes a 2-piece floating disc assembly, which contributes to reducing both rotating and unsprung weight. This floating design also mitigates the effects of extreme heat, preventing thermal stresses from warping the disc or affecting the braking surface. The rotors feature a unique slot design that minimizes braking noise and efficiently expels gases and pad debris. These rotors are heat-treated and balanced for optimal performance. Slotted rotors are recommended for vehicles primarily used for track driving, while cross-drilled rotors are suggested for daily driven vehicles as they tend to run cooler.\n\nApplication: This specific kit is designed for the 2008-2011 BMW M3 E90 Chassis Sedan, featuring a 330mm (13-inch) diameter slotted rotor and red 4-piston calipers.","brand":"Ksport","offers":[{"title":"Default Title","offer_id":52868437213496,"sku":"BKBM095-433SO","price":2293.25,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0970\/4895\/3144\/files\/687986985.webp?v=1787914151","url":"https:\/\/store.motormia.co\/products\/4-piston-caliper-front-big-brake-kit-with-slotted-rotors","provider":"MOTORMIA","version":"1.0","type":"link"}
