The Heritage Restoration for Version 5 & 6 GC8 STI.

The GC8 STI remains the benchmark for raw, mechanical driver connection. However, that connection is only as good as the hardware between your foot and the pressure plate. Decades of heat, moisture, and high-RPM shifting leave the original clutch linkage tired—resulting in a "mushy" bite point, inconsistent engagement, or a pedal that fails to return fully.

The Roo Racing GC8 Actuation Master Kit is a precision-curated collection of 100% Genuine Subaru components. Designed specifically for the pull-type 6-speed manual transmissions found in late-model Classic STIs, this kit replaces the high-stress pivot and sealing points that lead to transmission-out failures.

Why This Kit is Mandatory for the GC8:

  • Restore Mechanical Precision: We include the Genuine Subaru Release Shaft and Spring Pin. Replacing a grooved or rusted shaft is the single most effective way to eliminate "sticky" pedal syndrome and restore a crisp, predictable bite.

  • Heavy-Duty Structural Support: Our Genuine Subaru Release Fork is the reinforced pull-type design, engineered to withstand the increased clamp loads of modern "Stage" clutches without the risk of metal fatigue.

  • The "Zero-Leak" 10mm Seal: The early 5MT housings utilize the specific 10mm Hex Retaining Bung. We include a fresh Genuine replacement to ensure your transmission fluid stays in and contaminants stay out.

  • Era-Correct Environmental Sealing: Includes the Clutch Fork Dust Cover—a critical part that has often perished or gone missing on older chassis, leading to internal bellhousing corrosion.
