I have tried it and it gets rid of any turbo lag and the shift is much smoother. I am used to driving Vipers and this seems like a great way to ruin a clutch. He says its fine. What do the rest of you think? Is he as nuts as he sounds?
^That.

I am also coming from Viper with no hydraulic assist and I think I prefer the heavy feel vs. light.

The shifter itself feels just fine. I just can't seem to properly modulate the cluth for smooth shifting. Again, it's propbably purely operator error as opposed to mechanical issue...

NYNick is infamous around these parts
Having driven manual transmissions my entire life, and coming off a 2007 C4S, after a 2003 C4, and also owning a 65 Pontiac GTO, I was downright embarrassed taking my fellow 1996 Turbo owner out for a spin in my 2009TT the first day I got it. Bucking like a bronco, almost stalling, over revving...yikes, what's going on?
It's just a process of getting used to it. Completely different from all of the above, as is every clutch in e very car. Give it time.

A lot of valid points here. We sell quite a few GT2 conversions here and I'd have to say that 90% of our customers are happy with it. The other 10% feel that the pedal effort is way to hard for daily driving. Personally, I would trade the ambiguous, sloppy factory set up for the much harder, much more communicative GT2 set up any day if I were not driving the car in stop and go traffic on a daily basis. If the car is a daily driver and rush hour traffic is something that you will have to contend with I would advise against it. If the vehicle is more of a weekend warrior than a daily commuter then it's the GT2 conversion all the way, for me at least.

try using a more of a gradual 1 to 2, vs 1, 2 aka it's an H patter, go to the middle(netrual) and then into second in one gradual motion where you are counting 1 to 2 when doing it.

Sounds like you are letting out the clutch too fast and the engagement point is very small for this 997t.

Can't we tell him how to loosen his clutch line?

Not operator error. The engagement sucks, pure and simple.

Thank you so much for your input. I am happy to hear that I am not alone

Took the car in for some minor service and Porsche tech confirmed that turbo clutch blows relative to GT2/3 and even to non-turbo 997??

I Was a little shocked when I drove the 997tt vs my Gt3.. I thought how the hell is the clutch this heavy to hold 400hp all motor and the TT with all the HP/Tq has a feel like a civic.. I prefer the GT2 feel as well.. Something you can get more feedback from regardless of how heavy it is..

Maybe you'll let me try your GT3 clutch when I come over there.
