991.2 Manual Transmission Observations
I have driven a 6MT GT3 today as I am considering getting a GT3. I currently own a C7 ZR1, GT350, and a 991.2 GT3RS. The GT3 Manual would be a plus not a replacement. I had driven a manual GT3 before, but it was 1.5 years ago and I dont remember it much at this point. I dont know if the below observations is normal for this car.
- The shifter had a lot of play when in gear (while engine is running). Play means when you are in any gear, the shifter can move in any direction quite a bit.
- While car is in motion, loading the transmission by giving gas does noticeably move the shifter
- Clutch is very light
- Shifter feels much more rubbery than a 997 or a ZR1 shifter that has more metal feel to it
- Only in 1st gear, while shifting to 2nd at or around 3000 rpm, regardless of how quick or slow or smooth clutch is pressed, car lurches forward in a fairly jerky way. This happens upon engaging the clutch, not when disengaging it. The jerk does not happen in any other gear. It also does not happen in 1st gear in higher rpm. It is the low rpms where this is present. I tried it several times and I am sure it wasnt me or it wasnt random. I tried easing into the clutch or going quickly, didnt matter. Remember, this happens when you press the clutch not depress it.
Getting out of the car, into the ZR1, the shifter in ZR1 feels like bolt action rifle. There is no play in it and the clutch is much stiffer. Also this 1st gear lurching/jerk when engaging the clutch is a first for me. At this point, I must have accumulated 150,000 miles on performance manual transmission cars and never had this before. I dont think the GT3 I drove before did it. Maybe this car has a problem? Not sure. It did have 5000 miles.
Aside from this, comparing the base GT3 to the GT3RS, there is a substantial difference in steering, sound, braking (could be PCCB vs Steel though), and handling. They are very different cars (which solidifies my view of you need both). What surprised me most is how much quieter the cabin was in the GT3 and how soft the suspension was. The steering is also nowhere near as sharp and sensitive as RS. I think touring must be even softer.
Anyways, curious to hear people’s thoughts about the manual. Maybe the american cars are a bit overbuilt perhaps unnecessarily but I wouldnt want this sloppiness in the shifter when shifting at 9000 rpm. A lot less precise than I was hoping. Maybe the numeric shifter upgrade would address this?

I appreciate that. I didnt say its bad. It would be great if you and others could chime in on the specific observations I have made rather than saying its damn good which is very subjective. There is either move or not in the shifter. Whether you perceive the overall experience as good even if it has the move is your opinion - which isnt what I am after. I was more after whether my observations were inline with others.

I was doing some research on this and came across this post below. The first video is basically what I have experienced in the GT3 (even though the video is of GTS, I cant help but think GT3 shifter must be the same as far as components used albeit just shorter). The shifter I have in ZR1 feels I lot like the numeric shifter. I guess fix is easy, just upgrade the shifter and cables.

I have a GT3 with the Touring option. I don’t have a lot of play as you describe. The clutch is light especially compared to the 997 GT3 I had. In fourth gear the shifter does move somewhat under acceleration and also vibrates. Others have said this is because 4th is a direct gear. I also had a 991.2 RS which was very stiff compared to my car ( and also much stiffer than the 991.1 RS I had). My car is not jerky and does not lurch. I think the shifts are perfect for me and I wouldn’t change a thing.

My car does everything you describe, for the most part.
There is play in the shifter (not that bad, but more than my 997). I don't think it will move out of gear, but there is play
There is significant vibration in the shifter when accelerating.
Clutch is much lighter than my 997
There is some slight lurch forward as you say between 1st and 2nd, but it is actually less than in my 997. I just assumed this was normal with the lower RPM's.

It can be tough within the Porsche world to get accurate assessments. There is always the underlying current of it’s a Porsche so whatever it is, is the best. It’s a strong current.
I appreciate your feedback and effort to evaluate through a clear lens.

Clutch is a hydraulic clutch, light as usual. I've had many, recently, a Hellcat, clutch was heavy. This isn't a muscle car.
Video attached of Numeric.

What’s interesting to note the original design was never designed to have a manual as the 991.1 were all PDK. The manual in my speedster I love it, but to my earlier point wouldn’t be surprised to the fact the manual was only done due to the manual demand by enthusiasts. The 997 was made to have a manual vs the current.
