STI Quick Short Shifter Gear Kit – WRX & STI 6-Speed (GD/GG) ST350104S030

Every gear change should feel mechanical, precise, and satisfying — not soft or vague. The STI Quick Short Shifter Gear Kit tightens up the 6-speed’s feel with a factory-engineered 10% reduction in shift stroke, giving you faster, more direct shifts without compromising reliability.

Designed by Subaru Tecnica International (STI) for GD and GG-chassis WRX STI models, this kit replaces the standard linkage with a more aggressive setup tuned for performance driving.

Features:

• 10% Shorter Shift Stroke – quicker gear changes and tighter shift feel

• STI Factory Engineering – built for durability and OEM-level precision

• Improved Driver Feedback – solid, mechanical shift response you can feel

• Direct Fitment – designed for the 6-speed manual transmission (6MT)

• Hard Bushings – firmer engagement, minimal flex under load

Notes:

• The harder bushings may transmit some additional noise and vibration into the cabin — a small trade-off for the sharp, motorsport-inspired feel.

• Joint combination not included.

Fitment:

• Subaru Impreza WRX STI 2001–2007 (GD/GG 6MT)

• Compatible with STI 6-speed transmissions ST350104S030
