Thank you for the info. 20% shorter doesn't sound too much, and if you look at the photos in the Cayman brochure comparing the throws of the standard shifter and the sports shifter, the throw is shortened not by much, but I guess these data and photographs can never tell how the driver "feels" when using the sports shifter and I am glad you made the choice of installing one. I am persuaded.I have the sport shifter (XCZ) from the factory and can answer any questions you have have on it. My car is kept outdoors and temperatures go below 0 degrees C during the winter.
The shifter feels a bit rough in the cold, but nothing too annoying so don't let any talk about "hard to get into gear" hold you back on getting one.
I've had nothing but positive comments from other owners with stock shifters that have driven my car.
Let's see some photos of your Caymans around the city!
