The Mystery of the Golden Rabbit
- The Era: Conceived around 1998–1999, coinciding with Subaru’s peak golden age of rally dominance and the production of the iconic 22B.
The Build: Purported to feature high-end factory STI and motorsport components, including a tuned high-output engine, forged internals, upgraded chassis bracing, RAYS/BBS wheels, and aggressive aero enhancements.
The Disappearance: While appearing in early promotional materials, period tuning magazines, and concept displays like the Tokyo Auto Salon, it never materialized as a mainstream production car, leaving it a mythical ”unicorn” among JDM enthusiasts.
Subaru sold rare, factory-tuned versions of the Legacy through Subaru Tecnica International (STI) starting in the early 2000s. Rather than full standalone models like the WRX STI, these limited-run editions—such as the S401, S402, and ”Tuned by STI” variants—upgraded the performance, handling, and interior comfort of standard Legacy sedans and wagons.
