The A90 Supra has captured the hearts of car enthusiasts with its sleek design and impressive performance. However, to truly unlock its potential on the track or the street, upgrading the brake system is essential. This article will explore the benefits of upgrading to 6-piston calipers and high-performance rotors, providing you with the information needed to enhance your driving experience.
Why Upgrade Your Brake System?
Upgrading the brake system of your A90 Supra is crucial for several reasons:
- Improved Stopping Power: 6-piston calipers provide greater clamping force, leading to shorter stopping distances.
- Heat Dissipation: High-performance rotors are designed to withstand higher temperatures, reducing the risk of brake fade.
- Enhanced Performance: Upgraded brakes improve overall vehicle performance, especially during aggressive driving or track days.
- Increased Safety: Better brakes contribute to safer driving, allowing for more controlled stops in emergency situations.
Understanding 6-Piston Calipers
6-piston calipers are a significant upgrade over the standard brake calipers found in the A90 Supra. Here’s what you need to know:
- Design: 6-piston calipers consist of six pistons that evenly distribute clamping force across the brake pads, ensuring a more effective braking surface.
- Performance: The increased number of pistons allows for better modulation and responsiveness, making it easier to control braking force.
- Installation: Upgrading to 6-piston calipers may require additional modifications, such as new brake lines or brackets, to ensure proper fitment.
High-Performance Rotors
High-performance rotors are designed to complement the upgraded calipers, providing enhanced performance and durability. Consider the following features:
- Material: Many high-performance rotors are made from a composite material that offers better heat resistance and less warping.
- Ventilation: Slotted or drilled rotors improve airflow, allowing for better cooling during heavy braking.
- Weight: Lightweight rotors can reduce unsprung mass, improving handling and responsiveness.
Choosing the Right Brake System Upgrade
When selecting a brake system upgrade for your A90 Supra, consider the following factors:
- Driving Style: Choose components based on whether you primarily drive on the street, track, or in competitive racing.
- Budget: High-performance components can vary widely in price; determine your budget before shopping.
- Brand Reputation: Research brands and read reviews to ensure you’re purchasing reliable components.
Installation Process
Upgrading your brake system can be a complex process. Here’s a general overview of the installation steps:
- Preparation: Gather all necessary tools and components before starting the installation.
- Remove Wheels: Lift the vehicle and remove the wheels to access the brake components.
- Remove Old Calipers: Disconnect the brake lines and remove the existing calipers.
- Install New Calipers: Fit the new 6-piston calipers, ensuring they are securely attached.
- Install Rotors: Replace the old rotors with high-performance options, ensuring proper alignment.
- Reconnect Brake Lines: Reattach the brake lines and bleed the system to remove air bubbles.
- Reassemble: Reinstall the wheels and lower the vehicle.
Testing Your New Brake System
After installation, it’s essential to test your new brake system to ensure everything is functioning correctly. Follow these steps:
- Initial Brake Bedding: Follow the manufacturer’s instructions for bedding the new brakes to ensure optimal performance.
- Test Drive: Take your car for a test drive in a safe area to assess brake responsiveness and performance.
- Check for Leaks: Inspect the brake lines for any signs of leakage after the initial test drive.
Conclusion
Upgrading the brake system of your A90 Supra to 6-piston calipers and high-performance rotors is a worthwhile investment for any enthusiast looking to enhance performance and safety. With improved stopping power, heat dissipation, and overall driving experience, these upgrades are essential for both street and track use. Make sure to choose the right components, follow proper installation procedures, and test your system to enjoy the full benefits of your new performance brakes.
