The first-generation Acura NSX is renowned for its balance of performance and reliability. However, as with any high-performance vehicle, upgrading the braking system can significantly enhance driving experience and safety. This article discusses the installation of the AP Racing big brake kit (BBK) and the real-world performance results following the upgrade.
Understanding the Need for Brake Upgrades
The factory brakes on the first-gen NSX, while adequate for most driving conditions, can struggle under high-performance scenarios. Upgrading to a big brake kit can offer several benefits:
- Improved Stopping Power: Larger rotors and calipers provide increased friction and heat dissipation.
- Better Modulation: Enhanced pedal feel allows for more precise control during braking.
- Heat Management: Bigger brakes can withstand higher temperatures, reducing brake fade.
Choosing the Right BBK: AP Racing Overview
AP Racing is a well-respected name in the high-performance brake industry, known for their innovative designs and quality materials. Their big brake kits are engineered to provide optimal performance for both street and track applications.
Key Features of the AP Racing BBK
- Caliper Design: Lightweight aluminum construction with multi-piston designs for increased clamping force.
- Rotors: Larger diameter and vented rotors improve cooling and performance.
- Compatibility: Designed to fit within the stock wheel size while providing maximum performance.
Installation Process of the AP Racing BBK
The installation of the AP Racing BBK requires careful attention to detail and some mechanical knowledge. Here’s a step-by-step guide to the process:
Tools Required
- Socket set
- Torque wrench
- Brake line wrench
- Jack and jack stands
- Brake cleaner
Step-by-Step Installation
Follow these steps to successfully install the AP Racing BBK:
- Prepare the Vehicle: Park the NSX on a level surface, engage the parking brake, and lift the vehicle with a jack.
- Remove the Wheels: Take off the front wheels to access the brake components.
- Disconnect the Brake Lines: Use a brake line wrench to carefully disconnect the brake lines from the calipers.
- Remove Factory Calipers: Unbolt the factory calipers and remove them along with the rotors.
- Install New Rotors: Place the new AP Racing rotors onto the hub, ensuring proper alignment.
- Mount New Calipers: Position the new calipers over the rotors and secure them with the provided hardware.
- Reconnect Brake Lines: Attach the new brake lines to the calipers, ensuring a tight seal.
- Bleed the Brakes: Use a brake bleeder to remove any air from the brake lines.
- Reinstall Wheels: Put the wheels back on and lower the vehicle.
- Test Drive: Conduct a test drive to ensure proper brake function and performance.
Real-World Performance Results
After installing the AP Racing BBK, many NSX owners report significant improvements in braking performance. Here are some key observations:
- Reduced Stopping Distances: Many drivers experience a noticeable decrease in stopping distances, especially during aggressive driving.
- Enhanced Fade Resistance: The larger rotors and improved cooling capabilities reduce brake fade during extended use.
- Improved Pedal Feel: A firmer and more responsive pedal feel allows for better modulation and control.
Conclusion
Upgrading to the AP Racing big brake kit on the first-generation NSX is a worthwhile investment for both street and track enthusiasts. The installation process is straightforward for those with mechanical skills, and the real-world performance results speak for themselves. Enhanced stopping power, improved pedal feel, and better heat management make this upgrade a must for anyone looking to maximize their NSX’s performance.
