MIA's Description

The Kartboy Short Shifter is a direct replacement for the factory shifter in Subaru STI 6-speed manual models from 2004-2021, reducing shift throw by up to 40% and lowering the shift knob by 1 inch for a more precise and ergonomic feel. It is constructed from CNC-machined, TIG-welded 4130 Chromoly steel for durability.
