The BMW F90 M5 is a high-performance sedan that combines luxury with track-ready capabilities. One of the critical components that can significantly enhance its performance on the track is the braking system. Upgrading to 6-piston calipers and big brakes can provide improved stopping power, better heat dissipation, and overall enhanced performance during demanding driving conditions.
Understanding the Importance of Brake Upgrades
Braking performance is crucial for any high-performance vehicle, especially when it comes to track use. Upgrading your F90 M5’s brakes can lead to:
- Increased Stopping Power: 6-piston calipers provide more clamping force, resulting in shorter stopping distances.
- Improved Heat Management: Bigger brakes dissipate heat more effectively, reducing the risk of brake fade during prolonged use.
- Enhanced Modulation: Upgraded brakes allow for better pedal feel and control, giving drivers more confidence on the track.
Components of the Upgrade
When considering a brake upgrade for the F90 M5, several key components should be evaluated:
- 6-Piston Calipers: These calipers provide superior clamping force compared to the stock 4-piston calipers.
- High-Performance Brake Pads: Upgrading to pads designed for track use can improve bite and reduce fade.
- Slotted or Drilled Rotors: These rotors enhance airflow and cooling, further improving performance.
- Stainless Steel Brake Lines: Upgrading to stainless steel lines can reduce flex and improve pedal feel.
Benefits of 6-Piston Calipers
6-piston calipers are a popular choice for performance upgrades due to their numerous advantages:
- Better Clamping Force: More pistons mean greater force applied to the brake pads, enhancing stopping power.
- Even Pad Wear: The design distributes pressure evenly across the pad surface, leading to longer pad life.
- Improved Modulation: Drivers can achieve finer control over braking, which is crucial during track events.
Choosing the Right Brake Pads
When upgrading the braking system, selecting the right brake pads is vital. Here are some factors to consider:
- Material Composition: Choose pads made from high-friction materials designed for track use.
- Heat Resistance: Ensure the pads can withstand high temperatures without losing performance.
- Noise and Dust Levels: Consider pads that minimize noise and dust while providing excellent performance.
Rotors: Slotted vs. Drilled
When upgrading rotors, you’ll typically choose between slotted and drilled options:
- Slotted Rotors: These rotors have grooves that help with heat dissipation and reduce gas buildup, improving performance.
- Drilled Rotors: Holes in these rotors help with cooling but can be more susceptible to cracking under extreme conditions.
Installation Considerations
Proper installation of the brake upgrade is crucial for optimal performance. Here are some tips:
- Professional Installation: Consider having the upgrade installed by a professional to ensure safety and performance.
- Brake Fluid: Use high-performance brake fluid that can withstand higher temperatures.
- Brake Bedding: Follow a proper bedding procedure for the new pads and rotors to ensure optimal performance.
Conclusion
Upgrading to 6-piston calipers and big brakes on your F90 M5 can dramatically improve its track performance. With enhanced stopping power, better heat management, and improved modulation, these upgrades are essential for any serious track enthusiast. Ensure to choose quality components, consider professional installation, and follow proper maintenance practices for the best results.
