{"product_id":"supercomp-rear-big-brake-kit-61","title":"SuperComp Rear Big Brake Kit","description":"The Ksport SuperComp Rear Big Brake Kit (BKMD111-653CO) is engineered to deliver superior stopping performance for the Mercedes Benz W204 C-Class 4Matic. This kit integrates advanced brake technology to minimize brake fade and ensure consistent cooling of the brake pads during demanding use.\n\nAt the core of the SuperComp system is an extremely lightweight caliper, forged from aircraft-quality billet aluminum. This caliper features a differential bore configuration with significantly larger pistons than Ksport's ProComp calipers. Standard components include aluminum pistons, high-temperature seals, titanium brake pad retainer clips, and stainless-steel brake pad wear plates. The opposed piston caliper design dramatically improves pad wear and caliper rigidity compared to OEM setups, while the stainless-steel braided brake lines offer enhanced pedal feel and quicker response by preventing expansion under pressure. Due to the caliper's substantial size, each SuperComp caliper utilizes four brake pads.\n\nThe kit includes a 2-piece floating disc assembly, which reduces both rotating and unsprung weight. This floating design mitigates thermal stresses from extreme heat, preventing disc warping and cupping of the braking surface. The rotors feature a unique slot design that minimizes braking noise and efficiently expels gas and pad debris. Rotors are heat-treated and balanced for optimal performance. Cross-drilled rotors are recommended for daily-driven vehicles as they tend to run cooler, while slotted rotors are better suited for track-focused applications. Ksport SC5 Street Pads are included as standard, offering optimal braking for street and occasional track use with temperatures between 194°F – 1022°F. An option for Ksport RC5 Race Pads, designed for extreme track conditions with optimal temperatures between 482°F – 1472°F, is also available but not recommended for street use. All Ksport big brake kits come with a 12-month limited warranty against manufacturer defects.","brand":"Ksport","offers":[{"title":"Default Title","offer_id":52868571693368,"sku":"BKMD111-653CO","price":3675.79,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0970\/4895\/3144\/files\/687989904.jpg?v=1787915201","url":"https:\/\/store.motormia.co\/products\/supercomp-rear-big-brake-kit-61","provider":"MOTORMIA","version":"1.0","type":"link"}
