About Alcon Brakes
For over 30 years, Alcon has been at the forefront of high-performance and motorsport braking technology. Engineered in the UK to the highest tolerances, Alcon brake systems deliver uncompromising stopping power, pedal consistency, and durability. Whether you are daily driving, pushing for a PB at World Time Attack, or surviving a 24-hour endurance race, Alcon provides elite braking performance you can trust.
Choosing the Right Kit for Your Setup
To ensure you get the perfect Alcon kit for your BMW G-Series, it is crucial to match the brake system to your primary driving application and confirm your wheel clearance. Review the performance tiers below to select the right kit for your needs, keeping in mind the engineering requirements for Australian road use:
- Street Performance: Designed for spirited daily driving. These calipers feature standard dust boots for protection against the elements and can be engineered for legal road-worthy certification.
- Street/Track Performance: The ideal hybrid setup. Upgraded with high-temperature dust boots, this is a highly capable track caliper that can still be engineered for legal road-worthy certification.
- Track Performance: Dedicated motorsport braking. Built specifically for extreme conditions like WTAC, Time Attack, and Supersprints. These lack dust boots, are strictly off-road use only, and cannot be engineered for road-worthy certification.
- Endurance: Purpose-built for the longest stints on track. These high-performance calipers are designed for 6, 12, or 24-hour events and accommodate a minimum 25mm brake pad to ensure you make it to the checkered flag without a pad change.
