The BMW E39 M5 is a legendary performance sedan, known for its powerful V8 engine and dynamic handling. However, when it comes to track days, upgrading the braking system is essential for improved performance and safety. In this article, we will explore the best options for upgrading the E39 M5 brakes, focusing on pads, rotors, and calipers.
Understanding the Importance of Brake Upgrades
Braking performance is crucial on the track. The stock brakes may not provide adequate stopping power or heat dissipation under extreme conditions. By upgrading components, drivers can experience:
- Improved stopping power
- Better heat resistance
- Enhanced pedal feel
- Reduced brake fade
Choosing the Right Brake Pads
Brake pads are a critical component of the braking system. For track use, it’s important to select pads that can withstand high temperatures and provide consistent performance. Here are some recommended options:
- Ferodo DS2500: Known for excellent initial bite and fade resistance.
- Hawk HT-10: Offers high friction and is suitable for aggressive driving.
- EBC Yellowstuff: A good balance between street and track performance.
Upgrading Rotors for Better Performance
Rotors play a vital role in heat dissipation and overall braking efficiency. Upgrading to high-performance rotors can significantly enhance braking capabilities. Consider the following options:
- Slotted Rotors: Improve cooling and reduce brake fade.
- Drilled Rotors: Offer better heat dissipation but may wear pads faster.
- Two-Piece Rotors: Lighter and provide better performance due to reduced thermal expansion.
Caliper Upgrades for Enhanced Stopping Power
Calipers are responsible for clamping the brake pads against the rotors. Upgrading to larger or multi-piston calipers can provide significant improvements in braking force. Here are some options to consider:
- Brembo Calipers: Renowned for their performance and reliability.
- StopTech Calipers: Provide excellent modulation and fade resistance.
- AP Racing Calipers: Designed for high-performance applications with superior stopping power.
Installation Tips for Upgrading Brakes
Upgrading the brakes on your E39 M5 can be a rewarding project. Here are some tips to ensure a successful installation:
- Gather Tools: Ensure you have all necessary tools, including wrenches, sockets, and a brake bleeder.
- Follow Manufacturer Guidelines: Always refer to the installation instructions provided by the manufacturers.
- Bleed the Brakes: After installation, properly bleed the brake system to remove any air.
- Test Drive: Conduct a test drive to ensure everything is functioning correctly before hitting the track.
Conclusion
Upgrading the brakes on your E39 M5 for track days is a crucial step in enhancing performance and safety. By selecting the right pads, rotors, and calipers, drivers can ensure their vehicle performs at its best under demanding conditions. With proper installation and maintenance, these upgrades will provide a significant boost in braking performance, making track days even more enjoyable.
