History

Launched with a distinctive round-headlight face nicknamed 'bug-eye' by fans, the GDB STI continued Subaru's rally-derived engineering approach, adding a Driver Controlled Center Differential (DCCD) that let drivers manually adjust AWD torque split for changing conditions.

Why It Became Famous

It arrived during the most intense years of the Subaru-vs-Mitsubishi WRC rivalry, and its distinctive styling and rally-honed engineering made it one of the most recognizable and beloved Subarus ever built.

Strengths

  • Driver Controlled Center Differential allows genuine on-the-fly AWD torque adjustment
  • Stronger six-speed manual gearbox than the earlier GC8's five-speed
  • Distinctive, instantly recognizable 'bug-eye' styling with cult status
  • Same well-proven EJ-series boxer engine tuning ecosystem as the GC8

Weaknesses

  • Head gasket issues remain a known weak point on the EJ-series boxer engine
  • Distinctive styling is polarizing — some enthusiasts prefer later, more conventional facelifts
  • Values have risen as 2000s STI collector interest grows
  • JDM-only in early forms, requiring import in markets where it wasn't sold new

Common Problems

  • Head gasket failures typical of the EJ-series boxer engine family
  • Turbo and boost control wear on aggressively tuned examples
  • DCCD system wear or faults if not properly maintained
  • Rust in typical early-2000s Japanese sedan problem areas

Modification Potential

Excellent — shares the EJ-series platform's mature, well-documented tuning path, supporting big turbo upgrades and built engines with strong aftermarket parts availability worldwide.

Buying Guide

Verify head gasket service history, check DCCD system function, and confirm genuine STI equipment and documentation, especially for early JDM-only 'bug-eye' examples imported into other markets.

Enthusiast Popularity Today

Extremely popular among Subaru and rally enthusiasts, with the 'bug-eye' front end achieving genuine cult status despite its polarizing looks at launch.

Fun Facts

  • The 'bug-eye' nickname comes from its distinctive round headlight design used only in the earliest GDB model years
  • The Driver Controlled Center Differential (DCCD) let drivers manually bias AWD torque split from inside the cabin, a genuine rally-derived feature
  • This generation coincided with Subaru's fiercest WRC rivalry years against Mitsubishi's Lancer Evo
