The Subaru WRX is known for its performance and handling capabilities, but to truly unlock its potential, fine-tuning the suspension with adjustable coilovers can make a significant difference. This article explores how to achieve precise handling by adjusting camber, caster, and ride height on WRX coilovers.
Understanding Coilovers
Coilovers are a type of suspension system that combines the shock absorber and spring into a single unit. This design allows for adjustable ride height and can significantly impact the handling characteristics of a vehicle. For WRX owners, investing in quality coilovers is essential for optimizing performance.
Benefits of Adjustable Camber, Caster, and Ride Height
Adjustable camber, caster, and ride height are crucial for achieving the desired handling characteristics in the WRX. Each adjustment plays a unique role in the vehicle’s performance.
- Camber: This refers to the angle of the wheels in relation to the ground. Adjusting camber can improve tire contact with the road during cornering.
- Caster: This is the angle of the steering axis. Adjusting caster can enhance straight-line stability and steering feel.
- Ride Height: This affects the center of gravity and weight distribution, impacting handling and comfort.
Adjusting Camber
To adjust camber on WRX coilovers, follow these steps:
- Start by loosening the camber adjustment bolts on the top of the coilover.
- Use a camber gauge to measure the current camber angle.
- Adjust the camber by moving the top of the coilover in or out as needed.
- Tighten the adjustment bolts once the desired angle is achieved.
- Recheck the camber angle to ensure accuracy.
Adjusting Caster
Adjusting caster can be slightly more complex, but it is essential for improving steering feel. Here’s how to do it:
- Locate the caster adjustment bolts on the lower control arm.
- Loosen these bolts to allow for movement.
- Adjust the caster by moving the control arm forward or backward.
- Tighten the bolts once the desired caster angle is achieved.
- Use a caster gauge to verify the adjustment.
Adjusting Ride Height
Ride height adjustment is straightforward and can significantly impact handling. Follow these steps:
- Loosen the locking collars on the coilovers.
- Adjust the height by either raising or lowering the coilover unit.
- Ensure that both sides are adjusted evenly to maintain balance.
- Tighten the locking collars to secure the height setting.
- Recheck the ride height to confirm the desired setting.
Testing and Fine-Tuning
After making adjustments, it’s essential to test the vehicle to ensure the desired handling characteristics are achieved. Consider the following:
- Take the WRX for a test drive on various road conditions.
- Pay attention to steering response and stability during cornering.
- Make additional adjustments as necessary based on driving feedback.
- Revisit alignment settings after any significant adjustments.
Conclusion
Fine-tuning WRX coilovers through adjustable camber, caster, and ride height can dramatically enhance the vehicle’s handling and performance. By understanding and implementing these adjustments, WRX owners can achieve a more responsive and enjoyable driving experience.
