{"product_id":"extreme-lightweight-one-piece-caliper-kit-14","title":"Extreme Lightweight One-Piece Caliper Kit","description":"At the core of this kit is an extreme lightweight, one-piece caliper, CNC machined from aircraft-quality billet. This caliper boasts a differential bore configuration, weighs just over 5 lbs, and incorporates protection grooves for the bridge tubes. Standard features include aluminum pistons, high-temperature seals, and stainless-steel brake pad wear plates. The opposed piston caliper design fundamentally improves both pad wear and caliper rigidity compared to OEM setups. Additionally, stainless-steel brake lines are utilized to eliminate expansion under pressure.\n\nThe kit incorporates a 2-piece disc assembly, which effectively reduces both rotating and unsprung weight. For applications that generate extreme heat, a floating disc option is available to prevent thermal stresses from warping the disc or causing cupping of the braking surface. The unique slot design on the rotor actively reduces braking noise and more efficiently expels gas and pad debris compared to conventional designs. Each rotor is meticulously heat-treated and balanced prior to shipment to ensure optimal performance. For daily driven vehicles, cross-drilled rotors are recommended for cooler operation, while slotted rotors are best suited for vehicles with more track use.\n\nSpecific fitment for this rear 4-piston kit is for the 2009-2014 Infiniti FX37.","brand":"Ksport","offers":[{"title":"Default Title","offer_id":52868548362552,"sku":"BKIN060-447SO","price":3099.73,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0970\/4895\/3144\/files\/687989591.webp?v=1787914872","url":"https:\/\/store.motormia.co\/products\/extreme-lightweight-one-piece-caliper-kit-14","provider":"MOTORMIA","version":"1.0","type":"link"}
