{"product_id":"supercomp-8-piston-421mm-big-brake-kit","title":"Supercomp 8-Piston 421mm Big Brake Kit","description":"The Ksport Supercomp Big Brake Kit offers a significant upgrade in stopping power for your Mercedes Benz SLK R171 (2004-2011, models 280 and 350).\n\nThe SuperComp calipers are a standout feature, weighing just over 7lbs each and machined from aircraft-quality billet aluminum. They utilize a differential bore configuration with larger pistons than Ksport's ProComp calipers, and boast an opposed-piston design for improved pad wear and caliper rigidity. The calipers come standard with aluminum pistons, high-temperature seals, and stainless steel brake pad wear plates. This kit also includes a two-piece floating disc assembly with 421mm rotors that reduce rotating and unsprung weight. The unique slot design on the rotor helps expel gas and pad debris, while the two-piece construction minimizes thermal stress and prevents warping.\n\nThe kit comes complete with replacement calipers, rotors, pads, stainless steel brake lines, and all related hardware. Ksport offers a variety of rotor styles, including drilled and slotted options, as well as caliper color choices such as orange, red, yellow, black, and over 20,000 custom colors. For street use, SC5 Street pads are recommended, while RC1 Race Pads are available for track applications.","brand":"Ksport","offers":[{"title":"Default Title","offer_id":52868572414264,"sku":"BKMD120-971CO","price":5793.48,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0970\/4895\/3144\/files\/687988640.webp?v=1787915211","url":"https:\/\/store.motormia.co\/products\/supercomp-8-piston-421mm-big-brake-kit","provider":"MOTORMIA","version":"1.0","type":"link"}
