Product Description

The GrimmSpeed 380000 Shift Knob is a well-known upgrade in the Subaru/Toyota tuning community - combining robust stainless-steel construction with a weighted, ergonomic design for precise, confident gear shifts. The 675 g mass adds inertia to each shift, smoothing transitions and giving a heavier, more controlled feel under spirited driving or track-oriented shifts. Whether you prefer over-hand or side-grip shifting, the hybrid shape of this knob ensures comfort and control.

Installation is drastically simpler than many performance parts: the knob threads on to any manual shifter with M12x1.25 threads, requiring no adapters, wiring or fabrication. Because it's built from stainless steel and finished for durability, it stays resistant to wear and corrosion even through heavy use. For owners of manual-transmission Subarus, BRZ/86 models, or other compatible cars, the GrimmSpeed 380000 offers a direct-fit interior upgrade that significantly improves shift feel and adds a subtle but appreciated tactile enhancement to everyday driving or performance builds.
