The Nissan 370Z VQ37VHR is a popular choice among car enthusiasts looking to enhance their vehicles for track days. With its powerful engine and agile handling, the 370Z can be transformed into a formidable track machine with the right upgrades. In this article, we will explore essential modifications focusing on suspension, brakes, and power enhancements to help you build a 370Z that excels on the track.
Understanding the 370Z VQ37VHR
The Nissan 370Z is equipped with a VQ37VHR engine, a 3.7-liter V6 that produces impressive horsepower and torque. This engine, combined with a rear-wheel-drive layout, provides an exhilarating driving experience. However, to maximize its potential on the track, specific modifications are necessary.
Suspension Upgrades
A well-tuned suspension is crucial for improved handling and stability on the track. Here are some key suspension upgrades to consider:
- Coilover Kits: Upgrading to adjustable coilovers allows you to fine-tune ride height and damping settings, improving cornering performance.
- Sway Bars: Installing stiffer sway bars reduces body roll, enhancing the car’s responsiveness during high-speed turns.
- Strut Braces: Adding strut braces increases chassis rigidity, providing better feedback and stability while cornering.
- Upgraded Bushings: Replacing factory rubber bushings with polyurethane options improves suspension response and reduces flex.
Alignment and Corner Balancing
After installing suspension upgrades, a proper alignment is essential. A performance alignment focuses on maximizing grip and handling characteristics. Corner balancing ensures that each wheel has the correct weight distribution, optimizing performance during track sessions.
Brake System Enhancements
Upgrading the brake system is vital for track performance. Here are the main components to consider:
- Brake Pads: High-performance brake pads provide better stopping power and reduce fade during extended track sessions.
- Rotors: Upgrading to larger, slotted, or drilled rotors improves heat dissipation and braking performance.
- Brake Lines: Stainless steel braided brake lines enhance pedal feel and reduce flex, providing more consistent braking.
- Brake Fluid: Using high-temperature brake fluid helps prevent brake fade and maintains performance under extreme conditions.
Testing and Fine-Tuning Brakes
After upgrading the brake system, it’s essential to test the setup on the track. Pay attention to pedal feel, stopping distance, and heat management. Fine-tuning may be necessary to achieve optimal performance.
Power Enhancements
To maximize the VQ37VHR’s performance, consider the following power enhancements:
- Cold Air Intake: A high-flow cold air intake improves airflow to the engine, increasing horsepower and throttle response.
- Exhaust System: Upgrading to a cat-back exhaust system reduces back pressure and enhances exhaust note, resulting in better performance.
- Tune: A custom ECU tune optimizes engine performance, adjusting fuel maps and ignition timing for increased power.
- Forced Induction: For serious power gains, consider adding a supercharger or turbocharger kit to significantly boost horsepower.
Monitoring Performance
After making power enhancements, monitoring engine performance is crucial. Installing gauges for boost, air-fuel ratio, and oil temperature can help you keep track of your engine’s health and performance during track days.
Final Considerations
Building a 370Z VQ37VHR for track day requires careful consideration of suspension, brakes, and power enhancements. Each modification plays a vital role in improving overall performance and driving experience. Remember to regularly maintain your vehicle and make adjustments based on track feedback to ensure optimal performance.
With the right upgrades and tuning, your 370Z can become a track-ready machine, delivering exhilarating performance and handling on the racetrack.
