The suspension system of a WRX is crucial for performance, handling, and overall driving experience. Proper adjustments can lead to improved cornering, stability, and comfort. This guide will cover essential aspects of suspension adjustment, including alignments, corner weights, and more.
Understanding Suspension Basics
Before diving into adjustments, it’s important to understand the basics of suspension systems. The WRX utilizes a complex setup that includes various components working together to provide optimal performance.
- Shock absorbers
- Springs
- Control arms
- Anti-roll bars
Alignments: The Foundation of Suspension Setup
Alignment is a critical aspect of suspension setup. Proper alignment ensures that all four wheels are positioned correctly, which affects tire wear and handling.
Types of Alignments
- Camber: The angle of the wheels in relation to the vertical axis.
- Toe: The angle of the wheels in relation to the centerline of the vehicle.
- Caster: The angle of the steering axis in relation to the vertical axis.
Each type of alignment plays a significant role in how the car handles and performs on the road or track.
Adjusting Camber
Camber adjustments can be made using adjustable control arms or camber bolts. A negative camber can improve cornering grip, while positive camber can enhance stability in straight lines.
Adjusting Toe
Toe adjustments are typically made at the tie rods. Adjusting toe-in can improve stability, while toe-out can enhance cornering response.
Adjusting Caster
Caster adjustments are less common but can be modified with specific components. A positive caster angle can improve steering feel and stability during high-speed maneuvers.
Corner Weights: Balancing the Vehicle
Corner weighting is the process of distributing the weight of the vehicle evenly across all four wheels. This is crucial for maximizing grip and handling.
Why Corner Weights Matter
Uneven corner weights can lead to poor handling characteristics, such as understeer or oversteer. By ensuring that each wheel carries an equal load, the WRX can perform at its best.
How to Measure Corner Weights
To measure corner weights, you will need a set of scales designed for this purpose. Follow these steps:
- Place the scales under each wheel.
- Ensure the vehicle is on a level surface.
- Record the weight on each scale.
- Calculate the total weight and compare the corner weights.
Adjusting Corner Weights
Adjusting corner weights can be done by modifying the ride height using coilovers or adjusting weight distribution by relocating components within the vehicle.
Other Suspension Adjustments
In addition to alignments and corner weights, there are several other adjustments that can enhance the WRX’s suspension performance.
Ride Height Adjustment
Adjusting ride height can affect the center of gravity and overall handling. Lowering the vehicle can improve aerodynamics and cornering, while raising it can enhance off-road capabilities.
Damping Adjustments
Many aftermarket shock absorbers offer adjustable damping settings. Fine-tuning the damping can help control body roll and improve ride comfort.
Spring Rate Changes
Changing the spring rates can significantly alter the vehicle’s handling characteristics. Stiffer springs can improve responsiveness, while softer springs can enhance comfort.
Final Thoughts
Proper suspension adjustments are vital for maximizing the performance of your WRX. Understanding alignments, corner weights, and other adjustments can lead to a more enjoyable driving experience. Always consider your driving style and intended use when making these adjustments.
With the right knowledge and tools, you can transform your WRX’s suspension setup to meet your specific needs.
