Bmw M4 Performance Brake Upgrades: from Bbk Kits to Carbon-ceramic Discs for Track Days

by

The BMW M4 is a high-performance sports car that demands the best in braking technology, especially during track days. Upgrading the braking system can significantly enhance performance, safety, and overall driving experience. In this article, we will explore various performance brake upgrades, including Big Brake Kits (BBK) and carbon-ceramic discs.

Understanding the Importance of Brake Upgrades

Braking performance is crucial for any high-performance vehicle. The BMW M4, known for its speed and agility, requires a braking system that can handle the demands of both street and track driving. Upgrading the brakes can lead to:

  • Improved Stopping Power: Enhanced braking performance allows for shorter stopping distances.
  • Better Heat Dissipation: Upgraded brakes can manage heat better, reducing the risk of brake fade.
  • Increased Durability: Performance brakes are often more durable, providing consistent performance over time.

Big Brake Kits (BBK)

Big Brake Kits (BBK) are one of the most popular upgrades for the BMW M4. These kits typically include larger rotors, upgraded calipers, and high-performance brake pads. Here’s why BBK is a great choice:

  • Larger Rotors: Bigger rotors increase the surface area for braking, improving overall stopping power.
  • Multi-Piston Calipers: More pistons provide better clamping force and even pressure distribution.
  • High-Performance Pads: Upgraded pads enhance grip and reduce fade during intense driving.

Several manufacturers offer BBK options specifically designed for the BMW M4. Here are some top choices:

  • Brembo: Known for their racing pedigree, Brembo kits provide exceptional performance and reliability.
  • AP Racing: Offers lightweight and robust options for serious track enthusiasts.
  • StopTech: A popular choice for balanced performance and value, StopTech kits are great for both street and track use.

Carbon-Ceramic Discs

For those looking to take their BMW M4 to the next level, carbon-ceramic discs are an excellent upgrade. These discs offer numerous advantages over traditional iron rotors:

  • Weight Savings: Carbon-ceramic discs are significantly lighter, improving overall vehicle dynamics.
  • Heat Resistance: They can withstand higher temperatures without fading, making them ideal for track use.
  • Longevity: Carbon-ceramic discs typically last longer than traditional rotors, reducing replacement frequency.

Considerations for Carbon-Ceramic Discs

While carbon-ceramic discs offer many benefits, there are important considerations to keep in mind:

  • Cost: These discs are generally more expensive than traditional options.
  • Compatibility: Not all calipers are compatible with carbon-ceramic discs, so ensure proper fitment.
  • Daily Driveability: They may not perform optimally until they reach operating temperature, which can affect daily driving.

Choosing the Right Brake Upgrade

When selecting a brake upgrade for your BMW M4, consider the following factors:

  • Driving Style: Assess whether you prioritize street performance, track days, or a mix of both.
  • Budget: Determine how much you are willing to invest in brake upgrades.
  • Vehicle Use: Consider how often you drive your M4 on the track versus the street.

Installation and Maintenance

Proper installation and maintenance are crucial for maximizing the benefits of your brake upgrades. Here are some tips:

  • Professional Installation: Always consider having your brakes installed by a professional to ensure safety and performance.
  • Regular Inspections: Regularly check the condition of your brake components to identify any wear or issues.
  • Brake Fluid: Use high-performance brake fluid that can withstand higher temperatures.

Conclusion

Upgrading the braking system of your BMW M4 is a worthwhile investment for enthusiasts and track-day drivers alike. Whether you choose a Big Brake Kit or carbon-ceramic discs, the enhancements in performance, safety, and driving experience are undeniable. By carefully selecting the right components and ensuring proper installation and maintenance, you can enjoy the full potential of your M4 on the road and the track.
