{"product_id":"supercomp-forged-billet-aluminum-caliper-kit","title":"SuperComp Forged Billet Aluminum Caliper Kit","description":"The Ksport Supercomp Rear Big Brake Kit is engineered to provide superior stopping power for your Audi B9 A4. This high-performance upgrade integrates advanced brake technology to significantly reduce brake fade and ensure consistent pad refreshment under demanding conditions.\n\nThe SuperComp caliper, crafted from aircraft-quality billet aluminum, is exceptionally lightweight at just over 7 lbs. each. It features a differential bore configuration with larger pistons than ProComp calipers, offering enhanced braking performance. Standard inclusions are aluminum pistons, high-temperature seals, titanium brake pad retainer clips, and stainless-steel brake pad wear plates. The opposed piston design bolsters pad wear and caliper rigidity compared to OEM systems, while stainless-steel brake lines prevent expansion under pressure. Each caliper in the SuperComp series requires four brake pads due to its substantial size.\n\nThe kit utilizes a 2-piece floating disc assembly, which reduces both rotating and unsprung weight. This design also mitigates thermal stresses that can lead to disc warping or surface cupping under extreme heat. The rotors feature a unique slot design that minimizes braking noise and efficiently expels gas and pad debris. For daily driven vehicles, cross-drilled rotors are recommended for cooler operation, while slotted rotors are better suited for track use. Customers can choose between Ksport's SC5 Street Pads, designed for optimal street and occasional track performance with reduced dust and noise, or RC5 Race Pads, which offer maximum stopping power under extreme track conditions but are not recommended for street use due to their high operating temperature.\n\nThis big brake kit is made to order and is non-refundable. It is compatible with Audi A4 B9 models from 2017-2019 and B9.5 models from 2020-2025, specifically the 2.0T FWD variants.","brand":"Ksport","offers":[{"title":"Default Title","offer_id":52868425941304,"sku":"BKAU400-653CO","price":5914.18,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0970\/4895\/3144\/files\/687984406.jpg?v=1787914013","url":"https:\/\/store.motormia.co\/products\/supercomp-forged-billet-aluminum-caliper-kit","provider":"MOTORMIA","version":"1.0","type":"link"}
