Not sure if there's a thing for the Cayman/Boxster but almost every guy in my 997 chat with MT has installed the Numeric shifter to improve the action. The super long gearing is seriously annoying, I have 7 gears and use only 4, 1st,2nd, 3rd and 7th. What 4th through 6th are there for is beyond me. 3rd gear, WOT and the car is absolutely CLAPPING along at ferocious speeds and asking for more but I have to bail or risk jail time.
