What is a Short Throw Shifter?

A short throw shifter (STS) replaces the factory shifter with a unit that reduces the distance the shifter must travel between gear positions — the "throw." The factory STI shifter has a relatively long throw by performance car standards, requiring the driver to move the shifter a significant distance between gears. A short throw shifter reduces this distance, allowing faster gear changes with less hand movement. The reduction in throw is achieved by changing the geometry of the shifter lever — typically by shortening the lower portion of the lever (below the pivot point) relative to the upper portion, which reduces the arc the top of the shifter travels while maintaining the same transmission selector movement. The result is a more direct, precise, and engaging shifting experience.

GrimmSpeed STS — STI Platform Engineering:

GrimmSpeed has engineered their short throw shifter specifically for the Subaru STI's 6-speed transmission, ensuring the throw reduction and shift feel are optimized for the STI's specific transmission geometry and gate pattern. A poorly engineered short throw shifter can result in notchy, difficult gear engagement or missed shifts — GrimmSpeed's application-specific engineering ensures the STS provides a positive, reliable shift feel across all gear positions. The STI's 6-speed transmission is known for its precise, mechanical shift feel, and the GrimmSpeed STS enhances this character rather than compromising it.

6-Speed Only — Why It Matters:

The Subaru STI uses a 6-speed manual transmission across all model years from 2004-2021, while the WRX used a 5-speed (and later a 6-speed in some markets). The STI's 6-speed has different internal geometry, shift fork positions, and selector rod dimensions than the WRX's transmission. A short throw shifter designed for the STI 6-speed will not correctly interface with a 5-speed transmission, and vice versa. Always verify your vehicle has the STI 6-speed transmission before ordering. The GrimmSpeed GRM.1062.1.0 is specifically engineered for the STI 6-speed and should not be used in other applications.

Shift Feel — Managing Expectations:

A short throw shifter changes the throw distance and can affect the effort required to shift gears. Some short throw shifters increase shift effort slightly due to the changed lever geometry — this is normal and typically becomes less noticeable as the driver adapts to the new shifter feel. The GrimmSpeed STS is engineered to provide a positive shift feel without excessive effort. The shift throw reduction will be immediately noticeable — gear changes feel more direct and require less hand movement, which many drivers find more engaging and confidence-inspiring during spirited driving.

Pairing with Shifter Bushings:

For the best short throw shifter experience on the STI, pair the GrimmSpeed STS with upgraded shifter bushings. The factory STI shifter bushings are rubber and allow some flex and slop in the shifter assembly, which can make the shift feel vague even with a short throw shifter installed. Upgraded polyurethane or solid shifter bushings eliminate this flex, providing a more direct, mechanical shift feel that complements the reduced throw of the GrimmSpeed STS. Replacing the bushings at the same time as the shifter is recommended for the best overall shift feel improvement.

Why GrimmSpeed?

GrimmSpeed is one of the most respected Subaru performance parts manufacturers in the world, with a product line developed specifically for Subaru WRX and STI platforms. Their engineering focus on Subaru applications ensures their products are developed and validated for the specific requirements of the STI platform. GrimmSpeed's short throw shifter is trusted by STI enthusiasts worldwide for its quality construction, correct fitment, and genuine improvement in shift feel and speed.

Perfect For:

• 2004-2021 Subaru STI owners wanting faster, more precise gear changes
• STI track day and performance builds wanting improved shift speed
• Daily-driven STI builds wanting a more engaging, direct shift feel
• STI owners replacing a worn factory shifter with a performance upgrade
• Anyone seeking GrimmSpeed quality for their STI 6-speed drivetrain

Perfect For: 2004-2021 Subaru STI (6-speed) owners seeking GrimmSpeed short throw shifter for reduced throw, faster gear changes, and improved shift precision.

Pro Tip: Replace your shifter bushings at the same time — upgraded polyurethane bushings eliminate the flex and slop in the factory rubber bushings, and the combination of short throw shifter plus solid bushings provides a dramatically more direct and precise shift feel than either upgrade alone.

6-Speed STI Only: Reduced throw. Faster gear changes. Bolt-on installation. Fits 2004-2021 STI. Not for WRX or 5-speed applications. 1.3 lbs. Pair with upgraded shifter bushings for best results.
