Adjusting Lowering Springs for Track vs Street Use: Suspension Tuning Tips and Recommended Settings

by

When it comes to performance vehicles, the suspension setup plays a crucial role in determining how the car handles on different surfaces. Adjusting lowering springs for track versus street use requires understanding the distinct demands of each environment.

Understanding Lowering Springs

Lowering springs are designed to reduce the ride height of a vehicle, which can improve handling and aesthetic appeal. However, the spring rates and damping characteristics can vary significantly based on intended use.

Track Use vs. Street Use

Both track and street driving present unique challenges. Here’s how they differ:

  • Track Use: Focuses on maximum grip, stability, and responsiveness. The surface is typically smooth, allowing for stiffer setups.
  • Street Use: Prioritizes comfort and drivability. The roads may be uneven, requiring a softer suspension to absorb bumps.

Suspension Tuning Tips

When tuning your suspension, consider the following tips to optimize performance for either track or street use:

  • Spring Rates: Use stiffer spring rates for track use to minimize body roll and improve cornering. For street use, opt for softer rates to enhance comfort.
  • Damping Adjustments: Adjust the damping settings to match the spring rates. A higher damping rate is ideal for track settings, while a lower rate offers a smoother ride on the street.
  • Ride Height: Lowering the vehicle can enhance aerodynamics and center of gravity. However, ensure that the ride height is appropriate for the intended surface to avoid bottoming out.
  • Alignment Settings: For track use, consider a more aggressive alignment with increased negative camber for better cornering grip. Street setups should focus on a more neutral alignment for tire longevity.

Here are some recommended settings for tuning your lowering springs specifically for track use:

  • Spring Rate: 600-800 lbs/in (front), 400-600 lbs/in (rear)
  • Damping: 8-12 clicks from full stiff
  • Ride Height: 1.5 – 2 inches lower than stock
  • Camber: -2.5 to -3 degrees front, -1.5 to -2 degrees rear

For street use, your settings should focus on comfort while maintaining good handling:

  • Spring Rate: 300-500 lbs/in (front), 200-400 lbs/in (rear)
  • Damping: 4-6 clicks from full soft
  • Ride Height: 0.5 – 1.5 inches lower than stock
  • Camber: 0 to -1 degree front, 0 to -0.5 degree rear

Conclusion

Adjusting lowering springs for track versus street use is essential for optimizing vehicle performance. By understanding the differences in requirements and applying the recommended settings, drivers can achieve the best balance between comfort and performance.
