These M12x1.25 knobs are based off of GrimmSpeed's extremely popular line of existing shift knobs, just a bit shorter and rounder. They fit all manual Subarus and also work with the new generation of Ford Mustang and Focus RS! These knobs are made with a high quality, heavyweight 304 stainless steel. Weighing in at 600g, this knob will add an aggressive weighted feel each time you shift gears allowing you to shift faster and more smoothly than ever before. Each shift knob is laser etched around the base with the GrimmSpeed logo so that you know it's authentic.
