Upgrade the braking performance of your BMW GXX platform with the Alcon Big Brake Kit.
Engineered for high-powered street cars and weekend track machines, this kit is built to handle spirited driving, tuned builds, and demanding track use. Alcon’s motorsport-proven technology delivers maximum stopping power, reduced fade, improved pedal modulation, and superior thermal management — giving you confidence in every braking zone.
Each kit features lightweight, high-strength calipers paired with larger performance rotors.

This is a true bolt-on upgrade that integrates seamlessly with factory hubs and suspension geometry for hassle-free installation and reliable performance.
Features:
– Enhanced braking for street, track, and high-horsepower builds
– Lightweight aluminium calipers reduce unsprung weight and improve pedal feel
