Overview

The 034Motorsport 2-Piece Floating Rear Brake Rotor Upgrade is a complete replacement kit designed to work with factory rear calipers. It increases rotor diameter from 310mm to 350mm while reducing rotational weight by 1lb per corner. The rotors feature 72 directionally curved vanes for efficient cooling and a J-Slot slotted friction face. NVH levels are rated as None to Low, with potential for slight whirring noises due to performance-enhancing slots and vanes.
