The Subaru WRX is renowned for its all-wheel-drive (AWD) capabilities, providing exceptional handling and performance in various driving conditions. However, enthusiasts often seek to enhance this performance further through upgrades to the differential and limited-slip differential (LSD) options. This article explores the available enhancements for the WRX’s handling, focusing on differential upgrades and LSD options.
Understanding Differentials in the WRX
A differential is a crucial component in any vehicle’s drivetrain, allowing wheels to rotate at different speeds, particularly during turns. The WRX features a center differential as part of its AWD system, which distributes power between the front and rear axles. Understanding how differentials work can help you make informed decisions about upgrades.
Types of Differentials
- Open Differential: The standard differential that allows for maximum wheel speed variation but can lead to loss of traction.
- Limited-Slip Differential (LSD): Provides better traction by limiting the speed difference between wheels, improving handling in slippery conditions.
- Locked Differential: Forces both wheels to turn at the same speed, ideal for off-road conditions but can be less effective on pavement.
Upgrading the Center Differential
Upgrading the center differential can significantly impact the WRX’s handling characteristics. The following options are popular among enthusiasts:
- Active Center Differential: Offers adjustable torque distribution based on driving conditions, providing flexibility for performance tuning.
- Aftermarket Center Differential: Upgrading to a high-performance aftermarket option can enhance durability and responsiveness.
Enhancing Rear Differential Options
The rear differential plays a vital role in how power is distributed to the rear wheels, affecting cornering and stability. Here are some enhancements to consider:
- Performance LSD: Upgrading to a high-quality LSD can improve traction during acceleration and cornering.
- Adjustable Rear Differential: Some aftermarket options allow for tuning of the LSD’s characteristics to suit different driving styles.
Choosing the Right LSD for Your WRX
When selecting an LSD for your WRX, consider the following factors:
- Type of LSD: Choose between clutch-type, helical, or viscous LSDs based on your driving preferences.
- Driving Conditions: Consider how you use your WRX – daily driving, track days, or off-road – to select the appropriate LSD.
- Installation Complexity: Some LSDs require professional installation, while others can be installed as part of a DIY project.
Impact on Handling and Performance
Upgrading the differential and LSD options can lead to significant improvements in handling and overall performance. Here’s how these enhancements affect your WRX:
- Improved Traction: Enhanced LSDs provide better grip during acceleration, especially in wet or slippery conditions.
- Better Cornering Stability: Upgraded differentials help maintain stability during sharp turns, allowing for more aggressive driving.
- Customizable Performance: Adjustable differentials enable drivers to tailor handling characteristics to their preferences.
Installation Considerations
Installing upgraded differentials and LSDs requires careful consideration and planning. Here are some key points to keep in mind:
- Professional Assistance: If you’re not experienced with drivetrain work, consider hiring a professional to ensure proper installation.
- Compatibility: Verify that the parts you choose are compatible with your specific WRX model and year.
- Break-In Period: New differentials and LSDs may require a break-in period to achieve optimal performance.
Conclusion
Enhancing the Subaru WRX’s handling through differential and LSD upgrades can vastly improve driving experience and performance. By understanding the available options and their impacts, enthusiasts can make informed choices that align with their driving styles and conditions. Whether on the track or the street, these enhancements can elevate your WRX to new heights of performance.
