{"product_id":"procomp-8-piston-421mm-big-brake-kit","title":"Procomp 8 Piston 421mm Big Brake Kit","description":"The Ksport Procomp Big Brake Kit is a sophisticated bolt-on brake upgrade designed to deliver the highest level of stopping power for your 1999-2002 Nissan Skyline R34 Chassis.\n\nThis kit integrates new brake technology to significantly reduce brake fade and continuously cools the brake pad surface during braking. The extreme lightweight caliper, machined from aircraft quality billet, features a differential bore configuration and weighs just over 5 lbs. It includes aluminum pistons, high-temperature seals, and stainless steel brake pad wear plates, with an opposed piston design that enhances pad wear and caliper rigidity over OEM systems. Stainless steel brake lines are utilized to prevent expansion under pressure.\n\nThe 2-piece floating disc assembly included in this kit reduces both rotating and unsprung weight. This design also mitigates thermal stresses from extreme heat, preventing disc warping or cupping of the braking surface. The rotors feature a unique slot design that minimizes braking noise and efficiently expels gas and pad debris. For daily driven vehicles, the cross-drilled rotors are recommended as they tend to run cooler than slotted rotors.\n\nKey specifications include: Front position, 421mm (16.5in) rotor diameter, SuperComp 8 Piston caliper, red caliper color, and drilled rotor style.","brand":"Ksport","offers":[{"title":"Default Title","offer_id":52868662231352,"sku":"BKNS170-971CO","price":5266.8,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0970\/4895\/3144\/files\/687993367.webp?v=1787915688","url":"https:\/\/store.motormia.co\/products\/procomp-8-piston-421mm-big-brake-kit","provider":"MOTORMIA","version":"1.0","type":"link"}
