Subaru Wrx Sti Performance Brake Upgrades: from Slotted Rotors to Big Brake Kits for Track Use

The Subaru WRX STI is a high-performance vehicle that demands equally high-performance braking systems. Upgrading your brakes is essential, especially if you plan to take your car to the track. This article explores various performance brake upgrades, from slotted rotors to big brake kits, ensuring you have the stopping power needed for competitive driving.

Understanding Brake Upgrades

Before diving into specific upgrades, it’s important to understand what makes a brake system effective. Key factors include heat dissipation, stopping power, and pedal feel. Performance upgrades can enhance these aspects significantly.

Slotted Rotors

Slotted rotors are a popular upgrade for many performance enthusiasts. They feature grooves cut into the surface, which help in several ways:

  • Improved Heat Dissipation: The slots allow for better airflow, reducing the chances of brake fade.
  • Better Wet Performance: Slots help channel water away, improving grip in wet conditions.
  • Reduced Dust Build-Up: The design helps minimize brake dust accumulation.

When considering slotted rotors, it’s essential to pair them with high-performance brake pads to maximize their effectiveness.

Performance Brake Pads

Upgrading your brake pads is crucial for enhancing stopping power. Performance brake pads are designed to withstand higher temperatures and provide better bite. Key benefits include:

  • Increased Friction: Performance pads offer greater friction levels than standard pads.
  • Temperature Resistance: They maintain performance under extreme conditions.
  • Enhanced Feel: Improved pedal feel gives drivers more confidence.

When selecting brake pads, consider the type of driving you will be doing—track days require different pads than daily driving.

Big Brake Kits

For those looking for the ultimate in stopping power, big brake kits are the way to go. These kits typically include larger rotors, calipers, and upgraded hardware. Here are some of their advantages:

  • Increased Rotor Size: Larger rotors provide more surface area for heat dissipation.
  • Better Caliper Design: Multi-piston calipers offer improved clamping force.
  • Consistent Performance: They reduce brake fade during prolonged use.

Big brake kits can be more expensive but are often worth the investment for serious track enthusiasts.

Choosing the Right Upgrade

Choosing the right brake upgrade depends on various factors, including your driving style, budget, and intended use. Here are some considerations:

  • Driving Style: If you frequently track your vehicle, prioritize high-performance options.
  • Budget: Determine how much you are willing to spend, as upgrades can vary widely in cost.
  • Compatibility: Ensure that any upgrade is compatible with your specific WRX STI model.

Consulting with a professional or experienced enthusiasts can also provide valuable insights.

Installation Considerations

Installing performance brake upgrades can be a DIY project for some, but it’s essential to know your limits. Here are some tips:

  • Tools Required: Ensure you have the necessary tools, including jack stands, wrenches, and brake fluid.
  • Follow Instructions: Always follow the manufacturer’s instructions for installation.
  • Brake Bleeding: After installation, bleeding the brakes is crucial to remove air from the system.

If you’re not comfortable with the process, it’s best to seek professional help.

Maintenance of Upgraded Brakes

Upgraded brakes require regular maintenance to ensure optimal performance. Here are some maintenance tips:

  • Regular Inspections: Check for wear and tear on pads and rotors.
  • Brake Fluid Changes: Regularly change brake fluid to maintain performance.
  • Cleaning: Keep components clean to prevent dust and debris build-up.

Proper maintenance will extend the life of your brake upgrades and ensure safety on the road or track.

Conclusion

Upgrading the brakes on your Subaru WRX STI is a vital step for enhancing performance, especially for track use. From slotted rotors to big brake kits, the options are numerous, and each offers unique benefits. By understanding your needs and doing the necessary research, you can make informed decisions that will significantly improve your vehicle’s braking capabilities.
