GrimmSpeed Short Throw Shifter Subaru STI 2004-2021 | GRM.1062.1.0

Transform your shifting experience with the GrimmSpeed STI Short Throw Shifter, a precision-engineered upgrade designed from the ground up for 2004–2021 STI 6-speed models. Unlike modified factory levers or recycled designs, this is a true bolt-in performance shifter built for sharper engagement, improved feedback, and fully customizable feel—without sacrificing comfort or OEM compatibility.

Developed using full 3D scans of the factory shifter and linkage, this unit was modeled in CAD and extensively tested to ensure perfect fitment, optimal geometry, and a refined shifting action. The result is a shifter that delivers crisp, confident gear changes while maintaining a neutral knob position close to stock—even at shorter throw settings.
