NOT a Copolymer Shift Knob. Made from the superior material Delrin. Wonderful feel to this material, never too hot or too cold. The Delrin Shift Knob is strong enough to not require a brass insert to be used, and coincidentally the knob is stronger without an insert. It holds a thread very well too.
This simple design gives the best bang for your buck. Finish brushed for your viewing pleasure. Hand Polished Delrin knobs are available with a highly reflective surface and offer a ‘sticky’ feel suited for performance or track environments. These knobs do not wear! Fits all Subaru WRX and STI 6 speed manual transmission. Does NOT fit automatic transmission cars.
