The other obvious problem is that the stock shifter was attached to the torque tube....which was brilliant. As the engine and drivetrain moves around in the chassis, under G-forces, the shifter moved with it, which makes the "next gear" location very predicable in relationship to where the shifter is, when the shift movement is started.
With this shifter, which is now attached to the chassis, as the entire drivetrain shifts around in the chassis (under G-forces), the relationship of the gear pattern to the shifter is also going to move (this was a huge problem with the 964 race cars.......they were frequently shifted into the wrong gear, resulting in clutch, transmission, and engine destruction.) This, combined with the tiny amount of movement this shifter provides, is going to result in a much higher ratio of "incorrectly selected" gears.

If you are using tons of force to shift with my shifter then you are forcing the syncros to work much harder. I can shift my own car with 2 fingers with this short shifter. It is because this shifter has more feel, you feel the resistance of the syncros. With a factory shifter you have enough leverage to overcome the syncros, and therefor loose that feel. I think that I will have to finish up the last couple bits on my car, and then take a video of me driving it showing that it can be driven with little force. But I do have to disagree with you on the feel aspect. Less leverage results in more feel, more leverage results in less feel.

Another thing to note Greg,
As coming from a mechanical racing background, you should understand that one could weld another part onto the top of the shifter lever to be able to bring the shifter closer to the steering wheel, this added length would bring the throw back up to a longer reach, reduce the amount of force required, and reduce the distance between the steering wheel and shifter. All modern race cars you see have a massively tall shifter, or one very close to the wheel so that they car reduce the time the drivers hands are off the wheel to complete the shift.

Different strokes, for different folks.....just rendering my opinion.
Nothing you are going to say is going to make me like it....
I can see why some people would love it.....it makes them think they have a race car.
And, I completely understand why the OP is offering it for sale.....

just as an additional point of reference
Many years ago I replaced the bushing in my rear coupler on my race car with the aftermarket ones that were being sold to 911 owners.The aftermarket ones have a round hole where as the factory is oblong offering some fore/aft play. I did not care for it at all and went back to stock.
I guess we like what we like

Sorry to bump this iscussion again but I am still thinking about installing the lizard shifter but don't know if it will deliver whqt I am looking for. I want more precision but not neccesarily a short throw. I have fitted a new front cup and the aftermarket bushings in the back that have round holes.
Questions:
- could I fit the original shifter on to the lizard setup to get the original throw length but gain some shifing precision?
- how is the side-to-side movement of the shifter made? Fomthe puctures it looks like the shifter can't move side to side. Does it rotate at the fixing point?

I have the stock shifter and the best thing I ever did was put the new bushings in the rear. Made it like new again. One slight mod I did do is take a little off the top of the shifter. It shortens the throw slightly with keeping the factory setup.
