Impreza WRX STI Spec C

The Subaru Impreza WRX STI Spec C represents the ultimate lightweight track-focused variant of the STI, available exclusively in Japanese market across multiple generations. The Spec C features the EJ20 2.0-liter turbocharged flat-four producing 300-320 horsepower depending on generation (Japanese market power limit). Power is delivered through a close-ratio 6-speed manual transmission to Subaru's symmetrical all-wheel-drive system with driver-controlled center differential. The Spec C achieves weight reduction through aluminum hood, lightweight seats, reduced sound deadening, manual climate control, and smaller battery, saving approximately 110-180 pounds versus standard STI. Performance modifications include stiffer suspension, improved brakes, closer gear ratios, and revised ECU tuning. The Spec C represents pure STI performance with rally heritage, turbocharged flat-four power, all-wheel-drive capability, and lightweight construction for maximum driver engagement and track performance.
