{"product_id":"350mm-2-piece-floating-rear-brake-rotor","title":"350mm 2-Piece Floating Rear Brake Rotor","description":"The 034 Motorsport 2-Piece Floating Rear Brake Rotor is a direct replacement upgrade for MQB VW and Audi models, designed to seamlessly integrate with factory rear calipers. This kit offers a significant performance enhancement for street, track, and HDPE driving by increasing rotor diameter from 310mm to 350mm and reducing each rotor's weight from 15lbs to approximately 14lbs, thus decreasing rotational weight at each corner.\n\nEngineered for optimal thermal management, these rotors feature 72 directionally curved vanes that forcefully direct cool air through the disc to dissipate heat effectively. The rotor rings are constructed from a proprietary metal alloy capable of withstanding extreme braking temperatures while maintaining structural integrity. The central hat component is crafted from 6061-T6 aircraft specification aluminum, anodized with a Type III hard coating for durability. The J-Slot design on the friction face aids in cleaning the pad surface and allows for the release of hot pad outgassing. A sophisticated floating mount system, utilizing high-strength alloy steel bobbins, manages the axial and radial float between the hat and disc, accommodating thermal expansion and contraction safely.\n\nKey features include a lightweight 2-piece floating design, replaceable rotor rings for lower long-term maintenance costs, and OEM fitment for straightforward installation, which is rated as moderate. The NVH (Noise, Vibration, Harshness) levels are rated as none to low, though user feedback notes that NVH can be subjective and influenced by brake pad selection and other suspension components. Sounds associated with the J-slots and vanes are a direct result of performance enhancements. The kit includes the 034Motorsport 2-Piece Floating Rear Rotor Pair and caliper carrier conversion brackets.","brand":"034 Motorsport","offers":[{"title":"Default Title","offer_id":52686645068088,"sku":"034-301-2004","price":1289.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0970\/4895\/3144\/files\/657807726.webp?v=1784875590","url":"https:\/\/store.motormia.co\/products\/350mm-2-piece-floating-rear-brake-rotor","provider":"MOTORMIA","version":"1.0","type":"link"}
