2004 Subaru WRX STI Spec C

2004 to 2005 · Sedan

The Spec C represented Subaru's most hardcore STI variant during the GD generation, stripping weight and adding track-focused components for ultimate performance. The 2.0-liter EJ20 turbo produced 320 horsepower, paired with a close-ratio six-speed transmission and aggressive suspension tuning. Weight reduction measures included thinner glass, deleted sound deadening, and lightweight seats, creating a more focused driving experience than standard STIs. The Spec C's reputation was built on track dominance and razor-sharp handling that prioritized performance over comfort. Limited production and JDM exclusivity have made clean examples increasingly valuable, especially as enthusiasts recognize the Spec C as potentially the purest expression of Subaru's rally-bred philosophy. Values continue climbing as collectors seek the most authentic high-performance Japanese sedans from the golden era of turbocharged all-wheel-drive dominance.
