Audi RS5 B9 (2017-2024) ECR Racing 375mm Front & Rear 2-Piece Wavy Floating Brake Discs

Audi RS5 B9 (2017-2024) Front 375mm two-piece fully floating brake discs. ECR Racing brake discs feature a G3500 high-carbon outer brake disc mounted via floating bobbins to a 6061-T6 aircraft-grade aluminium top hat, giving exceptional thermal conductivity and the ability to handle severe heat cycling lap after lap on the racetrack, along with a useful weight saving over a standard disc. The bobbin mounting is what lets the outer brake disc expand safely under extreme heat instead of warping against a fixed, cast one-piece disc. Comes with our unique wavy-cut disc design for this line of vehicle, a circular disc face with a scalloped wave pattern machined into the edge. Sized to your vehicle's original brake disc dimensions for a straightforward swap.
