The GR86 is a popular choice among drifting enthusiasts due to its lightweight design and rear-wheel-drive layout. One of the key aspects to achieving optimal performance on the drift track is the proper adjustment of camber and toe angles. These adjustments can significantly influence the handling characteristics of your vehicle, allowing for improved control during drifts.
Understanding Camber and Toe
Before diving into the adjustments, it’s essential to understand what camber and toe are:
- Camber: The angle of the wheels in relation to the ground when viewed from the front of the vehicle. Negative camber means the top of the wheels is tilted inward.
- Toe: The angle of the wheels in relation to the centerline of the vehicle when viewed from above. Toe-in means the front of the wheels is closer together than the rear.
Why Adjust Camber and Toe for Drifting?
Adjusting camber and toe can enhance grip during cornering and improve stability while drifting. The right settings can help maintain tire contact with the road, allowing for better control and predictability. Here’s how each adjustment affects performance:
- Negative Camber: Increases tire contact during cornering, improving grip.
- Toe-Out: Enhances steering response and helps the car rotate more easily into corners.
Recommended Camber and Toe Settings
While the ideal settings can vary based on personal preference and driving style, the following are general recommendations for a GR86 used in drifting:
- Front Camber: -2.5 to -3.0 degrees
- Rear Camber: -1.5 to -2.0 degrees
- Front Toe: 0 to -0.1 degrees (slight toe-out)
- Rear Toe: 0 to +0.1 degrees (slight toe-in)
How to Adjust Camber
Adjusting camber on the GR86 typically involves modifying the suspension components. Here’s a step-by-step guide:
- 1. Raise the Vehicle: Use a jack to lift the car and secure it on jack stands.
- 2. Remove the Wheel: Take off the wheel to access the suspension components.
- 3. Adjust the Camber Bolts: Loosen the bolts on the upper control arm and adjust to the desired camber angle.
- 4. Check with a Camber Gauge: Use a camber gauge to measure the angle and make adjustments as necessary.
- 5. Reinstall the Wheel: Put the wheel back on and lower the vehicle.
How to Adjust Toe
Toe adjustments can be made using the tie rods in the steering system. Follow these steps for a proper adjustment:
- 1. Raise the Vehicle: Lift the car and secure it on jack stands.
- 2. Measure Current Toe: Use a tape measure to determine the distance between the front and rear of the tires.
- 3. Adjust Tie Rods: Turn the tie rod ends to achieve the desired toe setting.
- 4. Recheck Measurements: Measure again to ensure the toe is set correctly.
- 5. Lower the Vehicle: Remove the jack stands and lower the car.
Testing Your Settings
After making adjustments to camber and toe, it’s crucial to test the vehicle on the track. Pay attention to how the car handles during drifts and make further adjustments as necessary. Here are some tips for testing:
- 1. Start Slow: Begin with low-speed maneuvers to assess handling.
- 2. Gradually Increase Speed: Test at higher speeds to evaluate stability and grip.
- 3. Make Notes: Document how the car feels and any areas that need improvement.
Common Mistakes to Avoid
When adjusting camber and toe, avoid these common pitfalls to ensure optimal performance:
- 1. Over-adjusting: Making extreme adjustments can lead to unpredictable handling.
- 2. Ignoring Tire Wear: Monitor tire wear patterns to ensure settings are effective.
- 3. Neglecting Other Suspension Settings: Ensure that other suspension settings are balanced for best performance.
Conclusion
Adjusting camber and toe on your GR86 is essential for achieving better control during drifting. By understanding the effects of these adjustments and following the proper procedures, you can enhance your drifting experience. Remember to test your settings and make changes as needed to find the perfect balance for your driving style.
