The Renown Therapy Shift Knob has finally arrived. Years in the making with dimensions tested in many different machines, in all driving experiences. We wanted a motorsport derived knob, made locally here in San Francisco, California utilizing small batch manufacturing by enthusiasts, for enthusiasts. Our goal was to have a shift knob that would be a delight to use every day, yet feel perfect for spirited canyon runs to intense track battles. We have taken these knobs to the limit, on track at Laguna Seca, Sonoma and Thunderhill Raceway. We chose three finishes for a knob to fit every machine. Shiro = Opaque WhiteOat = Vintage Off-WhiteBlack Swan = Black Mounted with 2 offset, stainless steel allen set screws on the back, so unseen from the front. Included is also a solid brass insert that slides into the center hole, adding another 17 grams.
