The Toyota GR86 is a fantastic sports car, but to truly maximize its performance on the track, upgrading and tuning the suspension is essential. This article will guide you through the steps necessary to convert your GR86 suspension for optimal track performance.
Understanding the Basics of Suspension
Before diving into modifications, it’s crucial to understand the role of suspension in vehicle dynamics. The suspension system affects handling, ride quality, and overall performance on the track.
- Improves tire contact with the road
- Enhances stability during cornering
- Reduces body roll and pitch
Choosing the Right Suspension Components
There are several components to consider when upgrading your GR86 suspension:
- Coilovers: Adjustable coilovers allow you to fine-tune ride height and damping settings.
- Sway Bars: Upgrading sway bars can reduce body roll and improve cornering performance.
- Strut Braces: These improve chassis rigidity and handling response.
- Camber Plates: Adjustable camber plates allow for precise alignment adjustments.
Step-by-Step Suspension Upgrade Process
1. Gather Necessary Tools and Parts
Before starting the upgrade, ensure you have all necessary tools and parts. Common tools include:
- Jack and jack stands
- Wrenches and sockets
- Torque wrench
- Spring compressors
2. Remove the Stock Suspension
Begin by safely lifting the vehicle and removing the wheels. Follow these steps to remove the stock suspension:
- Detach the brake lines and sensors.
- Unbolt the strut assembly from the top and bottom.
- Carefully remove the stock springs using spring compressors.
3. Install New Coilovers
Once the stock suspension is removed, install the new coilovers:
- Place the new coilover assembly in position.
- Secure the top mount and lower bolts.
- Adjust the ride height according to your track specifications.
4. Upgrade Sway Bars
Replacing the sway bars will help minimize body roll:
- Remove the end links and bushings from the stock sway bar.
- Install the new sway bar with the provided bushings.
- Reconnect the end links to the new sway bar.
5. Install Strut Braces
Adding strut braces will enhance chassis rigidity:
- Locate the mounting points on the strut towers.
- Secure the strut brace using the provided hardware.
6. Fine-Tune Alignment and Camber
After installation, it’s essential to adjust the alignment:
- Use adjustable camber plates to set the desired negative camber.
- Ensure the toe settings are aligned for optimal handling.
Testing Your New Setup
After completing the suspension upgrade, it’s vital to test your GR86 on the track. Pay attention to the following:
- Handling response during cornering
- Ride comfort on straights and bumps
- Overall stability at high speeds
Common Issues and Troubleshooting
During testing, you may encounter some common issues:
- Too Stiff: Adjust the damping settings to soften the ride.
- Excessive Body Roll: Consider upgrading to thicker sway bars.
- Uneven Tire Wear: Double-check alignment settings.
Conclusion
Upgrading your GR86 suspension for track performance can significantly enhance your driving experience. By following the steps outlined in this guide, you can achieve a setup that maximizes handling, stability, and overall performance. Remember to test and adjust your setup based on feedback from the track to ensure optimal results.
