The BMW E39 M5 is a performance sedan that has earned its place in automotive history. Known for its powerful V8 engine and exceptional handling, the E39 M5 is a favorite among enthusiasts. However, to fully harness its capabilities, especially during track days, upgrading the braking system is essential. This article will explore performance brake upgrades, focusing on Brembo big brakes and upgraded rotors.
Why Upgrade Your Brakes?
Upgrading the brakes on your E39 M5 is crucial for several reasons:
- Improved Stopping Power: Enhanced braking systems provide better stopping distances, crucial for high-speed driving.
- Heat Dissipation: Upgraded brakes can handle higher temperatures, reducing brake fade during intensive use.
- Increased Pedal Feel: Performance brakes offer a firmer pedal feel, giving the driver more confidence and control.
Brembo Big Brake Kits
Brembo is a leading name in the world of performance brakes, and their big brake kits are designed to enhance the braking performance of the E39 M5 significantly. Here’s what you need to know about these kits:
Key Features of Brembo Big Brake Kits
- Large Calipers: Brembo kits typically feature larger calipers that increase clamping force on the rotors.
- Multi-Piston Design: Many kits utilize a multi-piston design, distributing braking force evenly across the pad surface.
- High-Performance Pads: The included brake pads are formulated for aggressive performance, providing better grip and longevity.
Installation Considerations
When installing a Brembo big brake kit, consider the following:
- Wheel Clearance: Ensure your wheels have enough clearance for the larger calipers.
- Brake Lines: Upgraded stainless steel brake lines may be necessary to accommodate the new calipers.
- Professional Installation: While some enthusiasts may opt for DIY, professional installation is recommended for optimal performance and safety.
Upgraded Rotors
In addition to caliper upgrades, replacing the rotors with high-performance options is essential for maximizing braking efficiency. Here are some considerations for rotor upgrades:
Types of Upgraded Rotors
- Slotted Rotors: These rotors feature grooves cut into their surface, helping to channel heat and gases away from the pads.
- Drilled Rotors: Drilled rotors have holes that reduce weight and improve cooling, but they may be more susceptible to cracking under extreme conditions.
- Two-Piece Rotors: Offering reduced weight and improved heat dissipation, two-piece rotors are an excellent choice for track performance.
Choosing the Right Rotors
When selecting upgraded rotors for your E39 M5, consider the following factors:
- Driving Style: Choose rotors that match your driving style, whether it’s street driving or track-focused.
- Material Composition: Look for rotors made from high-carbon or other performance materials for better heat management.
- Compatibility: Ensure the rotors are specifically designed for the E39 M5 to guarantee fit and performance.
Benefits of Upgrading Brakes for Track Days
For those who take their E39 M5 to the track, upgrading the braking system offers numerous benefits:
- Consistent Performance: Upgraded brakes maintain performance under repeated heavy braking, reducing the risk of fade.
- Enhanced Safety: Improved stopping power contributes to overall safety, allowing for quicker reactions on the track.
- Better Lap Times: With superior braking capabilities, drivers can carry more speed into corners, ultimately improving lap times.
Conclusion
Upgrading the brakes on your E39 M5 with Brembo big brakes and high-performance rotors is a worthwhile investment for any enthusiast. Not only does it enhance the car’s performance on the track, but it also ensures a safer and more enjoyable driving experience. Whether you’re a seasoned track veteran or a weekend warrior, these upgrades will help you unlock the full potential of your E39 M5.
