The Spec aluminum flywheel for Subaru WRX models built before July 2001 replaces the stock unit with a lighter rotating component intended for that production period. It’s specified for WRX applications produced prior to 7/2001 and serves as a direct replacement option when refreshing or upgrading the driveline. Choose this flywheel when restoring or maintaining period-correct Subaru WRX drivability and throttle response characteristics.
