{"product_id":"aerolite-4r-big-brake-kit","title":"Aerolite 4R Big Brake Kit","description":"The extreme lightweight, one-piece caliper is CNC machined from aircraft-quality billet, weighing just over 5 lbs. It features a differential bore configuration, machined protection grooves for the bridge tubes, aluminum pistons, high-temperature seals, and stainless-steel brake pad wear plates. The opposed piston caliper design enhances pad wear and caliper rigidity compared to OEM designs. Stainless-steel brake lines are included to eliminate expansion under pressure.\n\nThe kit utilizes a 2-piece disc assembly, reducing both rotating and unsprung weight. Many applications offer a floating disc option to mitigate thermal stresses and prevent warping or cupping of the braking surface under extreme heat. The unique slot design on the rotor minimizes braking noise and efficiently expels gas and pad debris. Every rotor is heat-treated and balanced before shipment to ensure optimal performance. Cross-drilled rotors are recommended for daily driven vehicles due to their cooler running characteristics, while slotted rotors are better suited for vehicles with more track use.","brand":"Ksport","offers":[{"title":"Default Title","offer_id":52865478721848,"sku":"BKSB010-653CO","price":3675.79,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0970\/4895\/3144\/files\/687994294.webp?v=1787888901","url":"https:\/\/store.motormia.co\/products\/aerolite-4r-big-brake-kit","provider":"MOTORMIA","version":"1.0","type":"link"}
