Adjusting Wrx Coilovers for Precision Handling: Techniques and Recommended Settings

by

The Subaru WRX is renowned for its performance and handling capabilities, and one of the best ways to enhance these attributes is by adjusting coilovers. Properly set coilovers can significantly improve ride quality and handling precision. This article will explore techniques and recommended settings for adjusting WRX coilovers.

Understanding Coilovers

Coilovers are suspension systems that combine springs and shock absorbers into a single unit. They allow for adjustable ride height and damping settings, making them popular among car enthusiasts.

  • Adjustable ride height
  • Customizable damping settings
  • Improved handling and stability

Tools Required for Adjustment

Before starting the adjustment process, ensure you have the following tools:

  • Jack and jack stands
  • Torque wrench
  • Spanner wrench
  • Measuring tape
  • Level

Adjusting Ride Height

Ride height adjustment is crucial for achieving the desired stance and handling characteristics. Here’s how to adjust it:

  • Start by parking the vehicle on a level surface.
  • Use a measuring tape to measure the distance from the ground to the fender arch.
  • Loosen the lock ring on the coilover using a spanner wrench.
  • Turn the adjustment collar to raise or lower the ride height.
  • Re-tighten the lock ring and re-measure to ensure accuracy.

Damping Adjustment Techniques

Damping affects how the suspension reacts to bumps and road imperfections. Here are techniques for adjusting damping:

  • Identify the type of damping adjustment: compression and rebound.
  • Start with the manufacturer’s recommended settings as a baseline.
  • Adjust compression by turning the knob clockwise for stiffer settings or counterclockwise for softer settings.
  • Adjust rebound in the same manner, focusing on how the car settles after a bump.
  • Test drive the vehicle after each adjustment to assess handling changes.

While settings may vary based on personal preference and driving style, the following recommendations serve as a good starting point:

  • Ride height: 1 to 2 inches lower than stock for improved handling.
  • Compression: 8-10 clicks from full soft for daily driving.
  • Rebound: 10-12 clicks from full soft for a balanced ride.

Testing and Fine-Tuning

After making adjustments, it’s essential to test and fine-tune the settings:

  • Take the car for a test drive on various road surfaces.
  • Pay attention to body roll, comfort, and responsiveness.
  • Make incremental adjustments based on your observations.
  • Repeat testing until you achieve your desired handling characteristics.

Common Mistakes to Avoid

When adjusting coilovers, avoid these common mistakes:

  • Not measuring ride height accurately.
  • Making drastic adjustments without testing.
  • Neglecting to tighten lock rings after adjustments.
  • Ignoring personal comfort preferences in handling settings.

Conclusion

Adjusting WRX coilovers can dramatically enhance your vehicle’s handling and performance. By following the techniques and recommended settings outlined in this guide, you can achieve precision handling tailored to your driving style. Remember to test and fine-tune your adjustments for the best results.
