The World’s Finest Shifting Experience

The wait is over—the ultimate shifting upgrade for your Subaru STI has arrived. The DM-1 Shifter, designed for 2008–2021 STI models, represents the pinnacle of performance shifting technology. Born from a relentless drive to push the limits, this patented design is handcrafted in the USA by DARKMATTERX and replaces the entire OEM assembly. The result is razor-sharp, mechanical gear changes that transform the driving experience and create an unbreakable connection between you and your Subaru.

 

Engineered for Precision and Performance

Every detail of the DM-1 Shifter is built to deliver stability, accuracy, and versatility. Its chassis-mounted construction locks the shifter firmly in place without requiring modifications, while the billet aluminum centering mechanism—with dual detents and a ceramic-coated torsion spring—guarantees perfect gear engagement and eliminates missed shifts. With the tool-free height adjustment, drivers can fine-tune shift knob position by over an inch, adapting quickly for both street and track use.

 

Thoughtful Design and Handcrafted Quality

The DM-1 goes beyond precision shifting with innovative features like the integrated cable-free reverse lockout, which combines 5th/6th gear stop reinforcement with precise reverse engagement, as well as the reinforced 1st/2nd gear stop for a firm, confident feel. Installation is straightforward—bolting directly into existing mounting points without special tools. Each unit is carefully hand-assembled and tested to ensure unmatched quality, and compatibility with both OEM shift knobs and the factory shift arm means it integrates seamlessly with any setup.

DM-1 V3 release notes:

• Reverse Lockout: The entire reverse lockout system has been consolidated into the housing of the shifter, eliminating the OEM reverse lockout cable.
• Non-adjustable 5th/6th/reverse Shift Stop: No adjustment necessary for the shift stop on the passenger side of the shift pattern. Shift stop is integrated onto the u-joint, saving space, install time, and also is a more robust system with increased feedback when engaging the stop.
• 1st/2nd Shift Stop: Shift stop is easier to adjust and integrated onto the housing of the shifter saving additional space and time during install. Rigidity is also increased to give an even firmer feel when engaging the stop.
• Centering Mechanism: Ceramic coating has been added to the torsion spring and hardware, along with an optimized design for a smaller form resulting in an easier install.
