{"product_id":"supercomp-rear-big-brake-kit-330mm","title":"Supercomp Rear Big Brake Kit 330mm","description":"The Ksport Supercomp Big Brake Kit is a high-performance rear braking system specifically designed for the Volkswagen MK4 Golf. This kit features a substantial 330mm (13-inch) diameter rotor with a 32mm thickness, paired with a robust 4-piston caliper. The SuperComp caliper itself is forged from aircraft-quality billet aluminum, designed with a differential bore configuration and larger pistons than Ksport's ProComp calipers, weighing just over 7lbs each. It includes aluminum pistons, high-temperature seals, titanium brake pad retainer clips, and stainless steel brake pad wear plates. The opposed piston caliper design significantly enhances pad wear and caliper rigidity compared to OEM systems, while the stainless steel brake lines resist expansion under pressure.\n\nThe kit utilizes a 2-piece floating disc assembly to reduce both rotating and unsprung weight. This floating design also mitigates thermal stress from extreme heat, preventing disc warping or cupping of the braking surface. The rotors feature a unique slot design that reduces braking noise and more efficiently expels gas and pad debris. Ksport offers both cross-drilled rotors, recommended for daily driven vehicles due to cooler operation, and slotted rotors, suggested for more track-focused use. Standard equipment includes Ksport SC5 Street Pads, composed of NAOC ceramic material designed for optimal street and occasional track performance with an operating temperature range of 194°F – 1022°F, offering reduced brake dust and noise. Alternatively, Ksport RC5 Race Pads, made of carbon metallic material, are available for extreme track conditions, with an optimal operating temperature of 482°F – 1472°F and not recommended for street use.","brand":"Ksport","offers":[{"title":"Default Title","offer_id":52869040210232,"sku":"BKVW041-436CO","price":2221.93,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0970\/4895\/3144\/files\/687997457.jpg?v=1787916370","url":"https:\/\/store.motormia.co\/products\/supercomp-rear-big-brake-kit-330mm","provider":"MOTORMIA","version":"1.0","type":"link"}
