The Subaru WRX GD series, known for its rally heritage and performance, often requires upgrades to its transmission and drivetrain to handle increased power and enhance reliability. This article outlines essential upgrades that can significantly improve the performance of your GD WRX.
Understanding the GD WRX Drivetrain
The GD WRX features a robust drivetrain designed for performance. However, as power levels increase, certain components may need reinforcement. The key components include:
- Transmission
- Driveshaft
- Differentials
- Clutch
Transmission Upgrades
One of the first areas to consider when upgrading your GD WRX is the transmission. The stock transmission can struggle under high power outputs, making upgrades essential for reliability.
Short Shifter Kits
Installing a short shifter kit can improve shift times and enhance driver engagement. This modification reduces the distance between shifts, allowing for quicker gear changes.
Heavy-Duty Gear Sets
Upgrading to heavy-duty gear sets can provide better strength and durability. These gears are designed to handle increased torque and power, reducing the risk of failure.
Transmission Mount Upgrades
Upgrading the transmission mounts can improve stability and reduce drivetrain movement during aggressive driving. Solid mounts can provide a more direct connection between the transmission and chassis.
Drivetrain Enhancements
The drivetrain components are critical for transferring power from the engine to the wheels. Upgrading these components can enhance performance and reliability.
Upgraded Driveshaft
A lightweight, upgraded driveshaft can reduce rotational mass and improve throttle response. Consider a one-piece driveshaft for better strength and reduced flex.
Differential Upgrades
The differentials play a crucial role in power distribution. Upgrading to a limited-slip differential (LSD) can improve traction and handling, especially during cornering.
Clutch and Flywheel Upgrades
A high-performance clutch is essential for handling increased power. Upgrading to a lightweight flywheel can also improve engine response and acceleration.
Suspension and Alignment Considerations
With increased power comes the need for improved suspension and alignment. Upgrades in these areas can help maintain handling and stability.
Performance Suspension Kits
Investing in a performance suspension kit can enhance handling and ride quality. Adjustable coilovers allow for customization based on driving style and conditions.
Alignment Adjustments
Proper alignment is crucial for tire wear and handling. After upgrading drivetrain components, ensure a professional alignment is performed to optimize performance.
Conclusion
Upgrading the transmission and drivetrain of your GD WRX is essential for handling increased power and ensuring reliability. By implementing these upgrades, you can enhance the performance and longevity of your vehicle, allowing you to enjoy the full potential of your Subaru WRX.
