{"product_id":"procomp-330mm-rear-big-brake-kit-1","title":"Procomp 330mm Rear Big Brake Kit","description":"The Ksport Procomp Big Brake Kit offers enhanced stopping power for your 2009-2013 Mercedes-Benz E350 W212 Chassis Coupe. Designed as a sophisticated bolt-on upgrade, this rear kit aims to significantly improve brake performance, reduce fade, and maintain pad surface integrity under sustained high-heat conditions.\n\nThis kit includes a lightweight, 4-piston ProComp caliper, machined from aircraft-quality billet and finished in red. The caliper features a differential bore configuration, aluminum pistons, high-temperature seals, and stainless steel wear plates for improved pad life and rigidity over stock designs. The opposed piston caliper design ensures better pad wear and increased caliper stiffness. It is paired with a 330mm (13-inch) slotted, 2-piece floating disc assembly. The floating design helps reduce rotating and unsprung weight while mitigating thermal stress to prevent disc warping.\n\nThe kit also includes stainless steel brake lines to prevent expansion under pressure, contributing to a more consistent pedal feel. The slotted rotor design is particularly recommended for vehicles that see more track time than daily driving, offering a balance of performance and noise reduction.","brand":"Ksport","offers":[{"title":"Default Title","offer_id":52868573692216,"sku":"BKMD191-433SO","price":2084.78,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0970\/4895\/3144\/files\/687988661.webp?v=1787915226","url":"https:\/\/store.motormia.co\/products\/procomp-330mm-rear-big-brake-kit-1","provider":"MOTORMIA","version":"1.0","type":"link"}
