The Subaru WRX STI is known for its impressive performance and handling, but one area that can always be improved is the braking system. Upgrading the brakes can enhance stopping power, improve pedal feel, and increase overall safety. In this article, we will explore various performance disc and pad options available for the Subaru WRX STI to help you make an informed decision.
Understanding Brake Components
Before diving into specific upgrades, it’s essential to understand the primary components of the braking system. The two main components that can be upgraded are the brake discs (rotors) and brake pads.
- Brake Discs (Rotors): These are the metal discs that the brake pads clamp down on to slow down the vehicle. Upgrading to performance rotors can improve heat dissipation and reduce brake fade.
- Brake Pads: Brake pads are the friction material that presses against the rotors. Performance pads can offer better grip and improved stopping power.
Performance Disc Options
When selecting performance discs for the Subaru WRX STI, there are several options to consider, each with its benefits.
- Slotted Rotors: These rotors feature grooves cut into their surface. The slots help to expel heat and gas, providing better performance during heavy braking.
- Drilled Rotors: Drilled rotors have holes that reduce weight and improve cooling. However, they may be more prone to cracking under extreme conditions.
- Two-Piece Rotors: These consist of a separate hat and disc, which can reduce weight and improve heat dissipation. They are often used in high-performance applications.
- Carbon-Composite Rotors: These are lightweight and provide excellent heat resistance but are typically more expensive. They are ideal for racing applications.
Performance Pad Options
Choosing the right brake pads is crucial for maximizing braking performance. Here are some popular performance pad options for the WRX STI:
- Street Performance Pads: These pads are designed for daily driving with improved stopping power and reduced dust. They offer a good balance between performance and longevity.
- Track-Day Pads: These pads are formulated for high-temperature performance, providing excellent grip during track use but may wear faster on the street.
- Race Pads: Designed for competitive racing, these pads offer the highest level of performance but may require heat to operate effectively.
- Low-Dust Pads: Ideal for those who want to keep their wheels clean, these pads produce less dust while still providing reliable stopping power.
Factors to Consider When Upgrading
When upgrading the brakes on your Subaru WRX STI, several factors should be considered to ensure you choose the right components for your needs.
- Driving Style: Consider how you primarily use your vehicle. Street driving, track days, and racing require different brake setups.
- Heat Management: Performance driving generates more heat. Ensure that the components you choose can handle the increased temperatures without fading.
- Budget: Performance upgrades can vary significantly in cost. Determine your budget and look for options that offer the best value for your needs.
- Compatibility: Ensure that any components you choose are compatible with your specific model year and any other modifications you may have made.
Installation and Maintenance
Proper installation and maintenance are crucial for maximizing the performance of your upgraded brakes. Here are some tips:
- Professional Installation: If you’re not experienced with brake installations, consider hiring a professional to ensure everything is done correctly.
- Break-In Period: New pads and rotors often require a break-in period. Follow the manufacturer’s recommendations to ensure optimal performance.
- Regular Inspections: Periodically check your brake components for wear and tear, especially after extensive driving or track use.
- Fluid Maintenance: Ensure your brake fluid is fresh and at the correct level to maintain optimal braking performance.
Conclusion
Upgrading the brakes on your Subaru WRX STI can significantly enhance your vehicle’s performance and safety. By carefully selecting the right performance discs and pads, considering your driving style, and ensuring proper installation and maintenance, you can achieve better stopping power and an overall improved driving experience.
