Upgrading the Vb Wrx Brakes for Track Days: Stops Under 100 Feet

by

When it comes to track days, performance is key, and one of the most critical aspects of performance is braking. Upgrading the brakes on your VB WRX can significantly enhance your stopping power, allowing you to stop in under 100 feet. This article will guide you through the process of upgrading your brakes for optimal performance on the track.

Why Upgrade Your Brakes?

Upgrading your brakes is essential for several reasons:

  • Improved Stopping Power: Enhanced brake components can reduce stopping distances significantly.
  • Heat Management: Better brakes can handle higher temperatures without fading.
  • Consistency: Upgraded brakes provide more consistent performance over repeated stops.
  • Safety: Increased braking performance contributes to overall safety on the track.

Key Components to Upgrade

When upgrading the brakes on your VB WRX, consider the following components:

  • Brake Pads: High-performance pads are designed for better grip and heat resistance.
  • Brake Rotors: Upgrading to slotted or drilled rotors can improve cooling and reduce brake fade.
  • Brake Lines: Stainless steel brake lines can enhance pedal feel and response.
  • Brake Fluid: Using high-temperature brake fluid can prevent vapor lock.

Choosing the Right Brake Pads

Selecting the right brake pads is crucial for track performance. Here are some factors to consider:

  • Friction Material: Look for pads made from semi-metallic or ceramic materials for better performance.
  • Temperature Range: Ensure the pads can operate effectively within the temperature range you’ll encounter on the track.
  • Noise Level: Track pads can be noisy; consider this if you plan to use your WRX on the street as well.

Upgrading Brake Rotors

Brake rotors play a vital role in the overall braking system. Here’s what to look for:

  • Type: Slotted or drilled rotors can help with heat dissipation and improve braking performance.
  • Material: Consider lightweight materials like carbon composite for better performance.
  • Size: Larger rotors can provide more surface area for better braking power.

Installing Stainless Steel Brake Lines

Stainless steel brake lines replace the factory rubber lines, providing numerous benefits:

  • Improved Pedal Feel: They reduce the sponginess often felt with rubber lines.
  • Increased Durability: Stainless steel lines are more resistant to wear and tear.
  • Better Response: They provide a more direct connection between the pedal and the brakes.

Choosing the Right Brake Fluid

Using the correct brake fluid is essential for high-performance braking. Consider the following:

  • Boiling Point: Choose a fluid with a high dry boiling point to prevent vapor lock during heavy braking.
  • Compatibility: Ensure the fluid is compatible with your brake system and components.
  • Type: Look for DOT 4 or DOT 5.1 fluids for track use.

Installation Process

Installing upgraded brakes can be done at home with the right tools. Here’s a general process:

  • Gather Tools: You’ll need a jack, jack stands, wrenches, and a brake bleeder.
  • Remove Wheels: Start by lifting the car and removing the wheels to access the brakes.
  • Replace Components: Swap out the old pads, rotors, and lines for the new upgrades.
  • Bleed Brakes: After installation, bleed the brakes to remove any air from the system.
  • Reinstall Wheels: Put the wheels back on and lower the car to the ground.

Testing Your Upgraded Brakes

After upgrading your brakes, it’s essential to test them before hitting the track:

  • Break Them In: Follow the manufacturer’s instructions for bedding in the new pads and rotors.
  • Test in Safe Conditions: Find an empty parking lot or a closed course to test stopping distances.
  • Monitor Performance: Pay attention to how the brakes feel and respond during initial tests.

Conclusion

Upgrading the brakes on your VB WRX is a valuable investment for any track enthusiast. With the right components and proper installation, you can achieve impressive stopping power, ensuring that you can stop under 100 feet. Always remember to test your upgrades thoroughly before hitting the track to ensure safety and performance.
