{"product_id":"supercomp-rear-big-brake-kit-59","title":"Supercomp Rear Big Brake Kit","description":"The Ksport Supercomp Big Brake Kit is engineered to provide superior stopping power for your Mercedes Benz W211 E-Class. This rear brake upgrade features a 356mm (14-inch) diameter, 32mm thick rotor assembly. The kit integrates advanced brake technology aimed at significantly reducing brake fade and ensuring continuous cooling and refreshing of the brake pad surface during braking.\n\nThe SuperComp caliper, forged from aircraft-quality billet aluminum, is extremely lightweight, weighing just over 7 lbs. It boasts a differential bore configuration with larger pistons than Ksport's ProComp calipers. Standard features include aluminum pistons, high-temperature seals, titanium brake pad retainer clips, and stainless-steel brake pad wear plates. The opposed piston design enhances pad wear and caliper rigidity, while stainless-steel brake lines prevent expansion under pressure. Due to the caliper's size, four brake pads are standard per caliper. The 2-piece floating disc assembly reduces rotating and unsprung weight, and prevents thermal stresses from warping the disc. The unique slot design on the rotor minimizes braking noise and expels debris, while cross-drilled rotors are recommended for daily drivers for cooler operation.\n\nThis kit includes Ksport SC5 Street Pads as standard, which are NAOC ceramic pads designed for optimal performance under street and occasional track conditions. They offer reduced brake dust, noise, and rotor wear compared to race pads, with an average coefficient of friction between 0.46 and 0.53. Optional Ksport RC5 Race Pads, made of carbon metallic material, are available for extreme track conditions with optimal operating temperatures between 482°F – 1472°F. These race pads are not recommended for street use. The kit is made to order and is non-refundable.","brand":"Ksport","offers":[{"title":"Default Title","offer_id":52868568154424,"sku":"BKMD080-447CO","price":3047.61,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0970\/4895\/3144\/files\/687987928.jpg?v=1787915155","url":"https:\/\/store.motormia.co\/products\/supercomp-rear-big-brake-kit-59","provider":"MOTORMIA","version":"1.0","type":"link"}
