Performance Suspension Setup for Miata Mx-5: Achieving a 1.0° Camber and 0.10° Toe for Track Days

by

The Miata MX-5 is renowned for its exceptional handling and driving pleasure, making it a favorite among track day enthusiasts. To maximize performance on the track, achieving the right suspension setup is crucial. This article will guide you through the steps to achieve a 1.0° camber and 0.10° toe for your Miata MX-5.

Understanding Suspension Geometry

Before diving into the specifics of camber and toe settings, it’s essential to understand what these terms mean and how they affect your vehicle’s performance.

  • Camber: The angle of the wheels in relation to the vertical axis of the car. Negative camber can improve cornering grip.
  • Toe: The angle at which the wheels point in relation to the centerline of the vehicle. Proper toe settings can enhance stability and responsiveness.

Tools Required for Suspension Setup

To achieve the desired camber and toe settings, you will need the following tools:

  • Camber gauge
  • Toe plates
  • Torque wrench
  • Jack and jack stands
  • Basic hand tools (sockets, wrenches, etc.)

Step-by-Step Guide to Achieving 1.0° Camber

Follow these steps to set your Miata MX-5 to a 1.0° camber:

  • 1. Raise the Vehicle: Use a jack to lift the front of the car and secure it with jack stands.
  • 2. Remove the Wheels: Take off the front wheels to access the suspension components.
  • 3. Adjust Camber Plates: If your Miata has adjustable camber plates, loosen the bolts and adjust until the camber gauge reads -1.0°.
  • 4. Tighten Bolts: Once the desired camber is achieved, tighten the camber plate bolts to the manufacturer’s specifications.
  • 5. Reinstall Wheels: Put the wheels back on and lower the car to the ground.

Setting the Toe to 0.10°

Once the camber is set, it’s time to adjust the toe settings:

  • 1. Measure Current Toe: Using toe plates, measure the distance between the front and rear of the wheels to determine the current toe angle.
  • 2. Adjust Tie Rods: To achieve 0.10° of toe, adjust the tie rods by turning them clockwise or counterclockwise as needed.
  • 3. Recheck Measurements: After adjustments, re-measure to ensure the toe is set correctly.
  • 4. Tighten Tie Rods: Once satisfied with the toe settings, tighten the lock nuts on the tie rods.

Testing Your Setup

After completing the suspension setup, it’s essential to test your Miata MX-5 to ensure everything is functioning as expected. Here are some tips for testing:

  • 1. Take a Test Drive: Drive your Miata on a track or a twisty road to feel how the new settings affect handling.
  • 2. Monitor Tire Wear: After several sessions, check your tires for uneven wear, which may indicate further adjustments are needed.
  • 3. Make Adjustments: If necessary, revisit the camber and toe settings to fine-tune performance.

Conclusion

Achieving a 1.0° camber and 0.10° toe on your Miata MX-5 can significantly enhance your track day experience. By following the steps outlined in this guide, you can ensure that your suspension setup is optimized for performance, providing better grip and handling on the track. Remember to regularly check and adjust your settings as needed to maintain peak performance.
