Product Description

The GrimmSpeed GRM.1062.1.0 is a fully adjustable short throw shifter engineered from the ground up for the 2004-2021 Subaru STI's 6-speed manual transmission. Unlike most short throw shifters that simply chop down the factory lever, GrimmSpeed reverse-engineered the entire OEM STI shifter and linkage assembly using 3D scanning and CAD simulation - then designed a purpose-built replacement with sealed Enduro MAX ball bearings, a feature exclusive to GrimmSpeed in this market. These bearings deliver 35-40% more load capacity than conventional radial bearings and resist contamination through double-lip labyrinth seals, ensuring consistent performance for the life of the part.

Throw reduction is adjustable from 0% to 26.3% with laser-etched reference marks for repeatable, precise setup, and the knob height can also be fine-tuned to match driver preference. The result is a direct bolt-in upgrade that immediately transforms the STI's shift feel - shorter, crisper, and more mechanical - without any permanent modifications. Not compatible with WRX 5-speed or WRX 6-speed transmissions.
