{"product_id":"supercomp-rear-big-brake-kit-90","title":"Supercomp Rear Big Brake Kit","description":"The Ksport Supercomp Rear Big Brake Kit offers a significant upgrade in stopping power for your Volkswagen MK4 Golf.\n\nThe SuperComp caliper is a key component, featuring a differential bore configuration with larger pistons than Ksport's ProComp calipers. Forged from aircraft-quality billet aluminum, each caliper weighs just over 7 lbs. and includes protection grooves for bridge tubes, 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 over OEM systems, while stainless-steel brake lines ensure a firm pedal by resisting expansion under pressure. Due to the caliper's size, each unit uses four brake pads.\n\nThe kit includes a 2-piece floating disc assembly, which contributes to reduced rotating and unsprung weight. This floating design also mitigates thermal stresses from extreme heat, preventing disc warping or cupping of the braking surface. The rotors feature a unique slot design to minimize braking noise and efficiently expel gas and pad debris. Customers can choose between cross-drilled rotors, recommended for daily-driven vehicles due to their cooler operation, or slotted rotors, better suited for track use.\n\nKsport offers standard SC5 Street Pads, composed of NAOC ceramic, designed for optimal performance in street and occasional track conditions with operating temperatures between 194°F – 1022°F. These pads reduce brake dust by over 50% compared to race pads and offer less noise and wear. Alternatively, RC5 Race Pads, made of carbon metallic, are available for extreme track conditions, operating best between 482°F – 1472°F and not recommended for street use.\n\nThis big brake kit is made to order and is non-refundable. It is compatible with the VW Golf\/GTI Mk4 (1999.5-2005) with 12v VR6 or 24v VR6 (2002+) engines.","brand":"Ksport","offers":[{"title":"Default Title","offer_id":52869040570680,"sku":"BKVW041-862CO","price":4586.51,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0970\/4895\/3144\/files\/687994966.jpg?v=1787916374","url":"https:\/\/store.motormia.co\/products\/supercomp-rear-big-brake-kit-90","provider":"MOTORMIA","version":"1.0","type":"link"}
