Rob Knob is the most bitching shift knob because it has a catchy name. A catchy gimmick to lure in the customers. Who cares about the scientific aspects if it looks really good in one color, as long as it's aluminum silver and it evokes memories of the ACS/SS kit, especially mated with the BL/SS kit with ERK. Now, I'll take my Rob Knob in Aluminum with the M logo. b. ------------------------------
