The Subaru WRX is known for its performance and handling capabilities. However, as enthusiasts push their vehicles beyond stock performance, upgrades become essential to maintain and enhance driving dynamics. One crucial upgrade is the Limited Slip Differential (LSD), which can significantly improve handling, especially when increasing horsepower to over 300 HP.
Understanding Limited Slip Differentials
A Limited Slip Differential is designed to improve traction by allowing for some degree of wheel slip while preventing excessive spin. This is particularly beneficial when cornering or driving on slippery surfaces, as it helps distribute power more effectively between the wheels.
Benefits of Upgrading to an LSD
Upgrading to a Limited Slip Differential offers several advantages, especially for Subaru WRX owners looking to enhance performance:
- Improved Traction: An LSD allows for better power distribution, enhancing grip during acceleration.
- Better Cornering: With improved wheel control, the vehicle can navigate turns more effectively.
- Reduced Tire Wear: By minimizing wheel spin, an LSD helps extend tire life.
- Increased Stability: Enhanced stability during high-speed maneuvers contributes to driver confidence.
Choosing the Right LSD for Your WRX
When selecting a Limited Slip Differential for your Subaru WRX, consider the following factors:
- Type of LSD: There are several types, including clutch-type, helical, and viscous. Each has its advantages and drawbacks.
- Gear Ratio Compatibility: Ensure the LSD is compatible with your existing gear ratios.
- Driving Style: Choose an LSD that suits your driving style, whether it be daily driving, track use, or off-road.
- Brand Reputation: Opt for trusted brands known for quality and performance.
Installation Process
Installing a Limited Slip Differential in your Subaru WRX can be a complex process, typically requiring mechanical expertise. Here’s a general overview of the steps involved:
- Gather Tools and Materials: Ensure you have the necessary tools, including a jack, jack stands, wrenches, and the new LSD.
- Remove the Driveshaft: Safely lift the vehicle and remove the driveshaft to access the differential.
- Drain Differential Fluid: Drain the existing fluid from the differential to avoid spills.
- Remove the Stock Differential: Detach the stock differential from the housing.
- Install the New LSD: Place the new LSD into the housing, ensuring it is secured properly.
- Reassemble Components: Reattach the driveshaft and any other components removed during the process.
- Refill Differential Fluid: Add the appropriate fluid to the new LSD.
Performance Improvements Post-Upgrade
After upgrading to a Limited Slip Differential, many WRX owners report noticeable performance improvements:
- Enhanced Acceleration: Improved traction allows for quicker launches and better acceleration out of corners.
- Sharper Handling: The vehicle feels more responsive and agile during turns.
- Increased Confidence: Drivers feel more in control, especially in challenging conditions.
Conclusion
Upgrading to a Limited Slip Differential is a worthwhile investment for Subaru WRX owners looking to enhance their vehicle’s performance, especially when pushing horsepower beyond 300 HP. With improved traction, handling, and overall stability, an LSD can transform your driving experience, making it more enjoyable and rewarding.
