Air Suspension Tuning for Track Use: Optimal Psi, Camber, and Dampening Settings

Air suspension tuning is a crucial aspect of optimizing vehicle performance for track use. Properly adjusting PSI, camber, and dampening settings can significantly enhance handling and stability, allowing drivers to achieve their best lap times. This article explores optimal settings for air suspension tuning on the track.

Understanding Air Suspension

Air suspension systems offer adjustable ride height and improved ride quality. They use air-filled bags instead of traditional springs, allowing for customization based on driving conditions. For track use, fine-tuning these systems is essential.

Optimal PSI Settings

PSI (pounds per square inch) settings are vital for achieving the desired stiffness and responsiveness from your air suspension. The optimal PSI can vary based on vehicle weight, track conditions, and tire specifications.

  • Lightweight vehicles: 30-35 PSI
  • Mid-weight vehicles: 35-40 PSI
  • Heavyweight vehicles: 40-45 PSI

These ranges serve as a starting point. It’s essential to experiment and adjust based on specific track feedback and personal driving style.

Camber Adjustments

Camber refers to the angle of the wheels relative to the vertical axis. Adjusting camber can significantly affect tire contact with the track surface, impacting grip and cornering performance.

Optimal Camber Angles

  • Front camber: -2.5 to -3.5 degrees
  • Rear camber: -1.5 to -2.5 degrees

Negative camber angles help improve cornering grip by ensuring that the tire maintains contact with the track surface during turns. However, excessive camber can lead to uneven tire wear and reduced straight-line stability.

Dampening Settings

Dampening controls the rate at which the suspension compresses and rebounds. Proper dampening settings are crucial for maintaining control and comfort during high-speed maneuvers.

  • Compression: 5-7 clicks from full soft
  • Rebound: 7-9 clicks from full soft

These settings provide a balanced response, allowing for quick recovery after bumps and maintaining tire contact with the track. Adjustments should be made based on feedback during practice sessions.

Track-Specific Considerations

Each track presents unique challenges that can affect air suspension tuning. Factors such as surface type, elevation changes, and cornering radius should influence your settings.

Surface Type

Tracks with rough surfaces may require softer settings to absorb bumps, while smoother tracks can benefit from stiffer settings for better responsiveness.

Elevation Changes

Tracks with significant elevation changes may necessitate adjustments to ride height and dampening to maintain stability during transitions.

Cornering Radius

Tracks with tight corners may require more negative camber and stiffer settings to enhance cornering performance, while long straights may allow for a softer setup.

Testing and Fine-Tuning

After making initial adjustments, testing your vehicle on the track is essential. Pay attention to how the car responds to inputs and make incremental changes based on performance.

Data Logging

Utilizing data logging tools can provide insights into suspension performance, helping you identify areas for improvement.

Driver Feedback

Listening to driver feedback is crucial for fine-tuning. Each driver may have unique preferences that can influence suspension settings.

Conclusion

Air suspension tuning for track use is a complex process that requires careful consideration of PSI, camber, and dampening settings. By understanding these elements and making informed adjustments, drivers can significantly enhance their track performance. Always remember to test and refine settings based on individual driving styles and track conditions for optimal results.
