DarkMatterX DM-1 Shifter - 2008-2021 Subaru STI

The Ultimate Shifting Upgrade

The wait is finally over—the DM-1 Shifter is here to redefine your Subaru STI driving experience. Designed for 2008–2021 models, this next-generation shifter represents the highest level of performance engineering. Handcrafted in the USA by DARKMATTERX, it replaces the entire OEM assembly and delivers crisp, mechanical precision with every gear change. The result is an unmatched level of control that creates a true connection between you and your car.

 

Built for Accuracy and Performance

From top to bottom, the DM-1 Shifter is engineered with stability and precision in mind. Its chassis-mounted design keeps the shifter firmly planted under extreme use, while requiring no vehicle modifications. Paired with a billet aluminum centering system featuring dual detents and a ceramic-coated torsion spring, it ensures flawless gear engagement and eliminates missed shifts. With the added benefit of tool-free knob height adjustment, you can fine-tune the setup instantly—perfect for both daily driving and track days.

 

Innovation Meets Handcrafted Quality

The DM-1 combines advanced design with meticulous craftsmanship. Its integrated reverse lockout system enhances rigidity for smooth engagement of 5th, 6th, and reverse gears, while the reinforced 1st/2nd gear stop delivers a reassuringly firm feel. Installation is simple and requires no special tools, using the factory mounting points for convenience. To ensure the highest standards, every shifter is hand-assembled and tested before leaving DARKMATTERX. With full compatibility for OEM shift knobs and the stock shift arm, the DM-1 blends seamlessly into your STI while taking shifting performance to a whole new level.

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.
