The DC Sports ERGO shift knob was explicitly created with the Toyota GR Corolla, GR Yaris, and GR86 / BRZ in mind. These shift knobs are machined from Delrin, which makes them more resistant to extreme changes in temperatures while being lightweight and durable.
This knob is direct threaded, so no adapter is needed or required. Each knob is threaded to M12x1.25 and is compatible with the Toyota reverse lock-out feature. No modifications are necessary.
Our knob weighs 94 grams. Available in Black or White Delrin.
