Handling and Cornering Improvements for a Track-ready Wrx Built Engine

by

The Subaru WRX is a popular choice among car enthusiasts, especially those looking to enhance their performance on the track. With its all-wheel-drive system and turbocharged engine, the WRX is already a formidable contender. However, to truly unlock its potential, handling and cornering improvements are essential. This article will explore various modifications and techniques to enhance the track readiness of a WRX built engine.

Understanding the Importance of Handling

Handling is crucial for any performance vehicle, particularly on a track where precision and control are paramount. Improved handling allows drivers to navigate corners more effectively, maintain higher speeds, and ultimately achieve better lap times. The following factors contribute to the overall handling of a WRX:

  • Suspension setup
  • Tire selection
  • Weight distribution
  • Chassis stiffness

Suspension Upgrades

One of the most significant areas to focus on for improved handling is the suspension system. Upgrading your WRX’s suspension can lead to better responsiveness and stability during cornering. Here are some key upgrades to consider:

  • Coilovers: Adjustable coilovers allow for precise tuning of ride height and damping, enabling better control over the vehicle’s dynamics.
  • Sway Bars: Upgrading to stiffer sway bars can reduce body roll during cornering, enhancing stability and grip.
  • Strut Braces: Installing strut braces can increase chassis stiffness, improving overall handling and response.

Tire Selection and Setup

The tires are the only contact point between the car and the track, making their selection and setup critical for performance. Consider the following when choosing tires for your track-ready WRX:

  • Tire Type: Opt for performance or track tires that offer better grip and responsiveness compared to standard road tires.
  • Tire Pressure: Adjusting tire pressure can significantly impact handling. Lower pressures can increase grip, while higher pressures can improve responsiveness.
  • Tread Pattern: Choose a tread pattern that suits the track conditions. Slicks are ideal for dry tracks, while tires with grooves are better for wet conditions.

Weight Distribution and Reduction

Proper weight distribution plays a vital role in handling. A well-balanced car will respond better to steering inputs and maintain stability during cornering. To achieve this:

  • Weight Reduction: Removing unnecessary weight from the car can enhance performance. Consider stripping non-essential components or using lightweight materials.
  • Ballast Placement: If weight reduction is not feasible, strategically placing ballast can help achieve a more balanced weight distribution.

Chassis Stiffening Techniques

A stiff chassis improves handling by reducing flex during cornering. Here are some techniques to increase chassis stiffness:

  • Roll Cages: Installing a roll cage not only improves safety but also adds rigidity to the chassis.
  • Underbody Bracing: Adding braces to the underbody can help stiffen the chassis and improve handling response.
  • Reinforced Mounts: Upgrading to reinforced engine and suspension mounts can reduce movement and enhance feedback from the road.

Alignment and Corner Balancing

After making significant modifications, it’s essential to have a proper alignment and corner balancing done. This ensures that all four tires are making optimal contact with the road. Here are the key aspects to focus on:

  • Camber Adjustment: Adjusting camber angles can improve tire contact during cornering, enhancing grip.
  • Toe Settings: Proper toe settings can affect steering response and stability. A slight toe-in can improve straight-line stability.
  • Corner Balancing: Ensuring that the weight is evenly distributed across all four corners can significantly improve handling and responsiveness.

Driving Techniques for Improved Cornering

While modifications can significantly enhance handling, driving techniques also play a crucial role. Here are some tips to improve your cornering skills:

  • Throttle Control: Modulating the throttle during cornering can help maintain traction and control.
  • Braking Techniques: Learn to brake effectively before entering a corner to transfer weight to the front tires, enhancing grip.
  • Look Ahead: Always look ahead to anticipate the corner and adjust your speed and line accordingly.

Conclusion

Improving the handling and cornering capabilities of a track-ready WRX built engine involves a combination of modifications and driving techniques. By focusing on suspension upgrades, tire selection, weight distribution, chassis stiffness, alignment, and honing driving skills, you can unlock the full potential of your WRX on the track. Remember, each modification should be tailored to your specific driving style and the track conditions to achieve the best results.
