Mercedes SL 63 AMG R231 (2012-) ECR Racing 360mm Front 2-Piece Floating Brake Discs

Mercedes SL R231 63 AMG (2012-2019) Front 360mm 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.
