Exedy Lightweight Flywheel – Subaru Models (inc. 2002-2005 WRX)

Exedy Lightweight Flywheel, 2002-2005 Subaru WRX

The Exedy Lightweight Flywheel for the 2002-2005 Subaru WRX reduces rotating mass at one of the highest-impact locations on the EJ20 drivetrain. The lightweight flywheel is manufactured from high-strength chromoly steel and is significantly lighter than the factory cast iron unit, the resulting reduction in rotational inertia produces a measurable improvement in throttle response and engine revving characteristics.

DETAILS

• Material: high-strength chromoly steel
• Significantly lighter than OEM cast iron flywheel
• Improved throttle response and engine revving
• Engineered for EJ20 WRX 5-speed application
• Fitment: 2002-2005 Subaru WRX EJ20

The flywheel is the largest rotating mass connected to the crankshaft. Reducing its weight produces a disproportionate improvement in engine response, the engine needs to accelerate less inertia every time the throttle is applied. On a performance platform like the EJ20 WRX, this reduction is felt immediately as a more eager, responsive engine character.

The Exedy flywheel is designed as a matched component for use with Exedy clutch kits, the friction surface is machined to the correct specification for Exedy Stage 1 through Stage 3 clutch discs, ensuring proper break-in and consistent contact across the full friction surface. The chromoly construction provides the strength needed to handle the clamp loads of performance clutch systems.

Why Choose Exedy

Exedy is the world’s largest clutch manufacturer and the OEM supplier to more than six major vehicle manufacturers globally, including Toyota, Honda, Subaru, and Mitsubishi. Every Exedy performance clutch is designed and manufactured as a purpose-built performance component, not a modified OEM part, not a remanufactured unit, but an engineered system built specifically for performance use from the ground up. Exedy’s research and development happens on actual race programs alongside their road car product development, meaning the technology that wins championships filters directly into the street performance catalog. When you install an Exedy clutch, you are installing a product from the company that builds the OEM clutch for the car it is replacing.

The RallySport Take

The Exedy lightweight flywheel for the 2002-2005 WRX is the correct upgrade at any clutch replacement, the incremental cost of upgrading the flywheel at clutch replacement time versus going back in to replace it later makes this the smart choice. Fits the 2002-2005 Subaru WRX with EJ20.
