The BMW M4 is known for its impressive performance and handling capabilities, making it a popular choice among car enthusiasts and track day participants. However, to maximize its potential on the track, upgrading the brakes is essential. This article will explore the various options for enhancing the braking system of the BMW M4, ensuring both performance and reliability during high-stress driving conditions.
Understanding the Importance of Brake Upgrades
Brakes are one of the most critical components of any performance vehicle, especially when it comes to track days. The stock brake system may not be sufficient for the rigorous demands of high-speed driving, which can lead to brake fade, longer stopping distances, and reduced overall performance.
Upgrading the brakes on your BMW M4 can provide several benefits:
- Improved Stopping Power: Enhanced brake components can significantly reduce stopping distances.
- Increased Heat Resistance: Upgraded materials can withstand higher temperatures, reducing fade during intense driving.
- Better Pedal Feel: Performance brake systems can offer a more responsive and consistent pedal feel.
- Enhanced Durability: High-performance brakes are designed to last longer under extreme conditions.
Key Components for Brake Upgrades
When considering brake upgrades for the BMW M4, it’s essential to focus on several key components:
- Brake Pads: Choosing the right brake pads can improve bite and reduce fade.
- Brake Rotors: Upgraded rotors can enhance cooling and provide better performance.
- Brake Calipers: High-performance calipers can increase clamping force and improve modulation.
- Brake Lines: Stainless steel lines can improve pedal feel and reduce expansion under pressure.
Brake Pads
Upgrading to high-performance brake pads is one of the most effective ways to enhance braking performance. Performance pads are designed to provide better grip and withstand higher temperatures without fading.
Some popular options for the BMW M4 include:
- Ferodo DS2500: Known for its excellent balance of performance and longevity.
- Brembo Sport Pads: Designed for high-performance applications with consistent braking power.
- Hawk HP Plus: Offers great bite and is ideal for track use.
Brake Rotors
Brake rotors play a crucial role in dissipating heat generated during braking. Upgrading to slotted or drilled rotors can enhance cooling and improve performance on the track.
Consider these options for your M4:
- AP Racing Rotors: Known for their durability and performance under extreme conditions.
- EBC Brakes GD Series: Features a unique design that improves airflow and cooling.
- Zimmermann Sport Rotors: Offers a balance of performance and affordability.
Brake Calipers
Upgrading the brake calipers can provide additional clamping force, which translates to better stopping power. Performance calipers are often lighter and designed to handle higher temperatures.
Some notable brands to consider include:
- Brembo Calipers: Renowned for their performance and engineering excellence.
- StopTech Calipers: Designed specifically for high-performance applications.
- AP Racing Calipers: Offers lightweight options for improved performance.
Brake Lines
Upgrading to stainless steel brake lines can enhance pedal feel by reducing flex under pressure. This upgrade can lead to more responsive braking, which is crucial during track events.
Some recommended brands include:
- Goodridge: Known for high-quality stainless steel brake lines.
- StopTech: Offers a range of performance brake lines that improve pedal response.
- OEM Replacement Lines: Sometimes, simply upgrading to OEM performance lines can yield significant improvements.
Additional Considerations
When upgrading the brakes on your BMW M4, it’s important to consider a few additional factors:
- Brake Fluid: Use high-performance brake fluid with a higher boiling point to prevent vapor lock.
- Brake Cooling: Consider installing brake cooling ducts to enhance airflow to the brakes.
- Regular Maintenance: Ensure regular checks and maintenance of the braking system to maintain performance.
Conclusion
Upgrading the brakes on your BMW M4 is a crucial step in enhancing its track day performance and reliability. By focusing on high-quality components such as brake pads, rotors, calipers, and lines, you can significantly improve your car’s stopping power and overall driving experience. Remember to consider all aspects of the braking system, including fluid and maintenance, to ensure your M4 performs at its best on the track.
