The DM-1 Shifter: Redefining Performance

Born from a lifelong obsession to push the limits of performance, the DM-1 Shifter represents the peak of shifting technology for the 2015–2021 Subaru STI. Handcrafted in the USA by DARKMATTERX, this complete replacement for the OEM assembly transforms every gear change into a razor-sharp, mechanical experience. Each shift creates a direct and unbreakable connection between you and your Subaru, blending precision, durability, and innovation into one mechanical masterpiece.

 

Precision-Built Components

The DM-1 Ultimate Shifter Kit includes the DM-1 Shifter, DM-1 Precision Shift Arm, DM-1 Shifter Box, and a premium Alcantara Shift Boot. Each part is carefully engineered to heighten performance while maintaining a factory-level fit. The shifter box, designed for 2008–2021 STI models, features a carbon fiber nylon body, closed-cell foam, and rubber seals for reduced noise and heat. A CNC-cut stainless panel, corrosion-resistant hardware, and a laser-engraved logo complete its stylish yet functional construction. The Alcantara Shift Boot adds a touch of sophistication with its ultra-soft texture and premium finish, commonly found in luxury European performance cars.

 

Innovative Features

The DM-1 Shifter brings together advanced engineering and user-focused design. Its chassis-mounted structure provides unmatched stability under extreme conditions while still using the OEM mounting points for a simple, modification-free installation. The billet aluminum centering mechanism with twin detents and a ceramic-coated torsion spring ensures precise engagement, eliminating missed shifts. With the tool-free adjustable shift height, you can quickly fine-tune the knob height by twisting the boot collar, tailoring your setup effortlessly for street or track use.

A fully integrated reverse lockout system combines improved rigidity and precision with the elimination of the OEM lockout cable, consolidating everything into the shifter housing. Additional features include the reinforced 1st/2nd gear shift stop, enhanced durability, ease of installation without special tools, and full compatibility with OEM Subaru shift knobs. Each shifter is hand-assembled and rigorously tested at DARKMATTERX, ensuring the highest standards of performance and reliability.
