It also fits the 2007-2009 Subaru Impreza WRX GT Spec B 2.5L Turbo 6-speed. By replacing the heavy OEM unit with this lightweight aluminum flywheel, the QR25DE spins up faster, throttle response sharpens noticeably, and the drivetrain sheds the inertia that blunts street

The friction surface geometry and clamp load requirements are matched to Clutch Masters pressure plates. Using an OEM clutch with this flywheel can result in premature wear or clutch failure.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eHow much lighter is this flywheel than the OEM unit?\u003c\/strong\u003e\u003cbr\u003eThis flywheel weighs approximately 8 to 11 lbs, compared to a typical OEM flywheel at 18 to 20 lbs. The reduction in rotating mass improves throttle response and lets the engine rev more freely throughout the powerband.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eIs this flywheel SFI certified?\u003c\/strong\u003e\u003cbr\u003eYes.

This is an expected characteristic of lightweight single-mass aluminum flywheels and does not indicate a defect. This product is intended for performance and competition use where this trade-off is acceptable.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eDoes this flywheel fit the 2007-2009 Subaru Impreza WRX GT Spec B?\u003c\/strong\u003e\u003cbr\u003eYes.
