About the Subaru Impreza WRX STI S204 GD
Released at the end of 2005, the S204 is the final and most refined limited edition of the GD-generation Impreza. Based on the 'Hawkeye' WRX STI, it features a hand-balanced EJ207 engine with a larger twin-scroll ball-bearing turbocharger and a titanium exhaust. The chassis was significantly upgraded with unique Yamaha-developed performance dampers designed to improve lateral rigidity and ride quality. Visually distinguished by its BBS forged wheels and carbon-backed Recaro bucket seats, it remains one of the most balanced and collectible Subarus ever produced.
