About Alcon Brakes

For over 30 years, Alcon has been at the forefront of high-performance motorsport braking. Engineered in the UK, Alcon brake systems deliver uncompromising stopping power and pedal consistency. Proven in the most demanding conditions, from sprint time attack to multi-hour endurance racing, where consistent thermal management is non-negotiable.

Mercedes-Benz CLA 45 (C117) / A45 (W176) AMG Fitment Guide

The M133 powertrain made the CLA 45 and A45 AMG two of the most potent hot hatches of their generation, and the 4MATIC drivetrain lets you carry serious speed into every braking zone. That performance comes with mass, and the factory front braking system runs out of thermal headroom quickly under sustained track use or once power is increased. These Alcon Big Brake Kits replace the OE setup with a full motorsport-derived package, shedding unsprung weight while massively increasing thermal capacity and pedal consistency.
