The Subaru WRX is renowned for its performance and handling, making it a popular choice among car enthusiasts and track day participants. However, to maximize its potential on the track, upgrading the braking system is crucial. This article delves into the essential components for enhancing your Subaru WRX brakes: performance pads, rotors, and additional stoppers.
Understanding the Importance of Upgraded Brakes
Braking performance is vital for any track day, as it directly influences lap times and overall safety. Stock brakes can quickly overheat and fade under the intense conditions of track driving. Upgrading to performance components ensures better heat dissipation, improved stopping power, and enhanced pedal feel.
Performance Brake Pads
Performance brake pads are designed to withstand higher temperatures and provide better grip compared to standard pads. They play a significant role in reducing stopping distances and improving overall braking performance.
Types of Performance Brake Pads
- Track-Only Pads: These pads offer the highest performance but may not be suitable for street use due to their cold bite.
- Street/Track Pads: A versatile option that performs well in both environments, providing a balance between daily drivability and track performance.
- Carbon-Ceramic Pads: These pads offer excellent heat resistance and longevity, ideal for serious track enthusiasts.
Upgrading Rotors
Rotors are another critical component of the braking system. Upgrading to high-performance rotors can significantly enhance braking efficiency and reduce fade during track sessions.
Types of Performance Rotors
- Slotted Rotors: These rotors feature grooves that help dissipate heat and gases, improving performance under heavy braking.
- Drilled Rotors: Drilled rotors provide excellent cooling but can be more prone to cracking under extreme conditions.
- Two-Piece Rotors: A lightweight option that reduces unsprung weight while maintaining strength and performance.
Additional Stoppers: Brake Lines and Fluid
To complete your brake upgrade, consider enhancing your brake lines and fluid. Stainless steel brake lines provide a firmer pedal feel and reduce flex under pressure. Upgrading to high-performance brake fluid is also essential, as it can withstand higher temperatures without boiling.
Benefits of Upgrading Brake Lines and Fluid
- Improved Pedal Feel: Stainless steel lines offer a more direct connection between the pedal and the brakes.
- Higher Boiling Point: Performance brake fluid can handle the heat generated during track use, reducing the risk of brake fade.
Choosing the Right Components for Your WRX
When selecting performance brake components for your Subaru WRX, consider your driving style and the specific demands of track days. Research various brands and read reviews to find the best options that suit your needs.
Recommended Brands
- Hawk Performance: Known for their high-quality brake pads that cater to both street and track use.
- StopTech: Offers a range of performance rotors and pads designed for serious enthusiasts.
- Goodridge: Renowned for their stainless steel brake lines that enhance braking performance.
Installation and Maintenance Tips
Upgrading your brakes can be a DIY project for those with mechanical skills, but professional installation is recommended for optimal performance and safety. Regular maintenance, including checking pad wear and rotor condition, is essential to ensure your braking system remains in top shape.
Maintenance Checklist
- Inspect brake pads for wear and replace as necessary.
- Check rotors for warping or cracking.
- Flush and replace brake fluid at recommended intervals.
- Ensure brake lines are free from leaks and damage.
Conclusion
Upgrading the brakes on your Subaru WRX for track days is an investment in performance and safety. By selecting the right performance pads, rotors, and additional components, you can enhance your driving experience and achieve better results on the track. Always prioritize quality and compatibility when making your upgrades to ensure the best performance.
