Check out my two new shift knobs. They are made from black and white acetal or delrin as some may know it. Along with my KB short shifter they make a great combination. What do you guys think? I prefer the black simply because it blends in with the interior but the white knob looks great also. They are much lighter than the stock leather knob and lighter than aluminum as well. No heat build up in the summer and they don't freeze the hands on those frigid mornings.
