Description
The EXEDY Performance Clutch Kit – 2004–2014 Impreza / 2007–2009 Legacy / 2017–2020 WRX STI (Subaru) is tailored to 2004–2014 Impreza / 2007–2009 Legacy / 2017–2020 WRX STI (Subaru) and is best considered when the goal is reliable torque transfer, predictable engagement, and hardware appropriate for enthusiast street, autocross, HPDE, and modified performance builds.
EXEDY Heritage
With roots in Japan dating to 1923, EXEDY has spent generations engineering clutches and powertrain components for both vehicle manufacturers and the aftermarket. That OEM foundation carries into its performance range, where organic, cerametallic, chromoly, and multi-plate technologies are developed for increasingly demanding street and competition applications.
How This Product Is Intended to Be Used
EXEDY's performance single- and multi-plate systems are intended to raise torque capacity and heat tolerance while matching the engagement characteristics to the car's intended use. Stage 1 uses an organic friction strategy for the most street-friendly behavior; Stage 2 moves to cerametallic friction for harder use; Hyper systems add dedicated flywheel and multi-plate architecture for substantially higher-output builds.
Choose the least aggressive configuration that comfortably covers the engine's torque and heat load. That approach normally gives the best balance of drivability, service life, transmission friendliness, and track durability.
Available Configurations
This parent listing contains multiple EXEDY configurations for the same application family. The differences below are functional and should be selected around torque demand, heat load, and acceptable engagement behavior.
| Configuration | EXEDY Part Number | Construction / Character | Torque Capacity | Recommended Use |
|---|---|---|---|---|
| Hyper Twin (FM022HR) | FM022HR | Twin-plate Hyper system with lightweight chromoly flywheel. Direct, motorsport-oriented engagement. | EXEDY general Hyper Twin family rating: approximately 500 ft-lb at the flywheel; verify the exact SKU/application | High-power street, drag, road-race and rally applications |
| Hyper Twin (FM022SDF) | FM022SDF | Twin-plate Hyper system with lightweight chromoly flywheel. Direct, motorsport-oriented engagement. | EXEDY general Hyper Twin family rating: approximately 500 ft-lb at the flywheel; verify the exact SKU/application | High-power street, drag, road-race and rally applications |
Selection Notes
The variants offered for 2004–2014 Impreza / 2007–2009 Legacy / 2017–2020 WRX STI (Subaru) are not cosmetic choices: each changes friction behavior, thermal capability, clamp-load strategy, or plate count. Match the selection to actual engine torque, tire grip, vehicle weight, launch frequency, and street-versus-track duty rather than simply choosing the most aggressive option.
Engineering Details
- Clamp Load: Stage 1/2 covers are designed around roughly 40% higher clamping load than the genuine part
- Pedal Effort: Typical Stage 1/2 increase is approximately 20–35%, application dependent
- Flywheel Compatibility: Stage 1/2 generally use the OEM flywheel unless noted; Hyper systems include/require their dedicated flywheel
- Certification: EXEDY Stage 1, Stage 2 and Lightweight Flywheel products are SFI 1.1 certified
- Vehicle Application: 2004–2014 Impreza / 2007–2009 Legacy / 2017–2020 WRX STI (Subaru)
- EXEDY SKUs: FM022HR, FM022SDF
Application-specific construction notes: Cerametallic friction.
Fitment note: Because clutch fitment is sensitive to transmission and flywheel changes, verify the complete vehicle configuration before purchase. Modified swaps or previously converted flywheel systems may require a different EXEDY part than a stock vehicle.
