AP Racing Pro 5000R 378mm Front Brake Kit – BMW E9X M3
Product Description
The AP Racing Pro 5000R Front Brake Kit (378x36mm) for the BMW E9X M3 platform is a serious braking upgrade developed for fast road, track day and motorsport applications. Built around AP Racing's renowned Pro 5000R six-piston forged aluminium calipers, the system delivers exceptional stopping power, improved pedal feel and significantly increased thermal capacity over the factory braking system.
Using large 378x36mm two-piece front discs, lightweight aluminium bells and precision-engineered mounting hardware, the kit substantially improves heat management and braking consistency during repeated heavy braking. The larger disc diameter and motorsport caliper design increase braking torque and resistance to brake fade, making the system ideally suited to demanding track environments and high-performance road use.
Customers can choose between genuine AP Racing discs/rotors or a more cost-effective aftermarket two-piece disc/rotor option. At Clubsport Garage we have extensively tested the aftermarket rotor assemblies on our own F87 M2 Competition track car with excellent results in terms of performance, durability and consistency. Several customers previously running AP Racing rotor assemblies have also moved to the aftermarket setup and reported similarly positive results, making them a compelling option for customers looking to reduce long-term running costs without compromising braking performance.
AP Racing Pro 5000R calipers do not utilise dust seals. This motorsport-focused design allows reliable operation at significantly higher temperatures than conventional road calipers. Vehicles used regularly on the road may require more frequent inspection and cleaning, particularly during harsh weather conditions.
An optional anti-rattle pad retention spring kit is available separately for customers wanting to minimise brake pad movement and reduce unwanted noise during everyday driving.
Caliper Options
CP9660 Pro 5000R
The standard six-piston forged aluminium caliper, offering exceptional braking performance, pedal feel and thermal management for fast road, track day and motorsport use. The CP9660 utilises an 18mm pad thickness, providing excellent performance while maintaining a compact package and reduced unsprung mass.
CP9668 Endurance Pro 5000R
An endurance-focused six-piston forged aluminium caliper designed around increased pad volume and improved heat management during prolonged heavy braking. The CP9668 utilises a larger 25mm pad thickness, increasing available friction material for improved heat capacity, extended pad life and reduced service intervals during intensive track use or endurance applications.
