My OPC fitted one on my 997TT and I am loving it! First couple of changes on a cold morning can be a bit stiff, but not a real problem. IMHO it improves the the experience
I have the option on my new '09. I like it don't love it yet. on my 996 turbo I loved it! Perhaps it will be better after the car has a few miles on it. I do vote that it is an option worth having. Get it!
