BMW M4 F82 (2014-2020) ECR Racing 380mm Front & Rear 2-Piece Floating Brake Discs

BMW M4 F80 (2014-2018) Front & Rear 380mm two-piece fully floating brake discs. ECR Racing brake discs feature a G3500 high-carbon drilled 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 a specially designed drilled pattern as standard. Sized to your vehicle's original brake disc dimensions for a straightforward swap.
