The Subaru WRX, particularly the GD model, has long been a favorite among automotive enthusiasts. With its rally heritage and turbocharged power, it’s no wonder that many owners seek to push their vehicles beyond the factory limits. When tuning your WRX to handle 400+ horsepower, one of the most crucial upgrades is the clutch. A performance clutch can significantly improve your driving experience, especially for aggressive driving styles.
Understanding Clutch Upgrades
Before diving into specific upgrades, it’s essential to understand the function of the clutch in your vehicle. The clutch connects and disconnects the engine from the drivetrain, allowing for smooth gear changes. As power increases, the stock clutch may struggle to handle the added stress, leading to slippage, overheating, and ultimately, failure.
Benefits of Performance Clutch Upgrades
Upgrading to a performance clutch offers several benefits for those pushing their WRX to higher power levels:
- Improved Power Handling: Performance clutches are designed to handle higher torque and horsepower levels.
- Enhanced Durability: Built with stronger materials, they resist wear and heat better than stock clutches.
- Better Engagement: A performance clutch offers a more responsive and precise engagement, improving driving feel.
- Reduced Slippage: With increased clamping force, these clutches minimize slippage during aggressive driving.
Types of Performance Clutches
When selecting a performance clutch for your GD WRX, there are several types to consider:
- Organic Clutches: These provide a good balance of performance and drivability, making them suitable for street use.
- Feramic Clutches: Known for their durability, feramic clutches can handle high power but may sacrifice some drivability.
- Metallic Clutches: These are designed for extreme performance, offering excellent heat resistance and power handling, but can be harsh on drivability.
- Single vs. Twin Disc: Single disc clutches are common for most applications, while twin disc setups offer even higher performance but at a higher cost.
Top Performance Clutch Options for GD WRX
Here are some of the top performance clutch options available for the GD WRX that can handle 400+ horsepower:
- Exedy Stage 1 Clutch Kit: Ideal for street performance, it offers a great balance of power handling and drivability.

- Clutch Masters FX400: A popular choice among enthusiasts, this clutch provides excellent engagement and can handle significant power.
- Competition Clutch Stage 2: Designed for high-performance applications, it offers great torque capacity and quick engagement.
Installation Considerations
Installing a performance clutch is a complex task that requires mechanical knowledge and the right tools. Here are some considerations:
- Professional Installation: Unless you are experienced, it’s recommended to have a professional install your new clutch.
- Flywheel Replacement: Consider replacing the flywheel with a lightweight option for better performance.
- Break-In Period: Most performance clutches require a break-in period to ensure optimal performance.
- Clutch Line Upgrade: Upgrading to a stainless steel clutch line can improve pedal feel and responsiveness.
Maintaining Your Performance Clutch
To ensure longevity and optimal performance from your upgraded clutch, regular maintenance is essential:
- Regular Inspections: Check for signs of wear or damage periodically.
- Fluid Changes: Keep the clutch fluid fresh to prevent contamination and maintain performance.
- Avoid Overheating: Be mindful of heat buildup during aggressive driving, as excessive heat can damage the clutch.
- Practice Smooth Driving: Smooth engagement and disengagement can extend the life of your clutch.
Conclusion
Upgrading the clutch in your GD WRX is a vital step when pushing for 400+ horsepower. A performance clutch not only enhances power handling but also improves the overall driving experience. By understanding the different types of clutches available and choosing the right one for your driving style and needs, you can enjoy the full potential of your WRX while ensuring reliability and performance on the road.
