Numeric Short Shifter / Cables

PJ can comment more, but I have sat in PJ's car with the CAE shifter. It is very similar in feel to the Numeric gate to gate BUT there is a huge difference in the strength of the centering spring (since CAE has their own), which makes the shifting feel more like a sequential AND the shifter is raised and much closer to hands on the wheel. So yeah, completely different!
Oh, and I agree with Mooty, the biggest bang for the buck are the cables. The rest is just tweaking. Also, for 90% of us, you don't need to shift faster, so a short shifter is shortening the life of your transmission. The good news is the Numeric has the long throw setting which matches the standard shifter in the GT3, which is where mine is set.

Installing my Numeric today. Couple things:
1. If you have RSR shift cables, (car came this way) you need to remove post from the shift cable bracket, or 5th and 6th are not smooth.
2. Make sure all the centering washers for the stock shifter where it mounts are out of the way, one of mine was hiding.
3. Also the lateral shift cable attachment was missing a bolt, M6 fits great, lucky I have a full assortment of leftovers from many jobs...

The Numeric guys are great. They are local here in Tampa and actually they get their Cupcar serviced at our shop. The shifters are awesome. We had a few loaners that we would install before guys went to the track. Afterwards they all convert. It really makes that much of a difference.

Great feedback. Please elaborate on the centering spring, which one do you favor? CAE or Numeric? Would like to hear your thoughts on how the short shifter shortens the life of the transmission as well, this may be a learning I can benefit from to avoid unnecessary wear / stress on the device. I'm looking for precision and therefore efficiency, my current OEM short shifter "feels" like it's stressing the system the accomplish its task...I always feel that if you're trying too hard, you're doing something wrong which is why I want to make the change. Short isn't my issue, lack of precision is.
Thanks in advance...Mike.

Regarding short shifters- I'm just repeating what I've heard from people that rebuilt my transmission and from other gear experts. As you move faster from gate to gate you are "rushing" the synchro's and wearing them out faster. On 997.2 GT3's the 2nd gear synchro is brass which wears quickly. When my transmission was regeared with 3.89 RS final drive gearing my second gear synchro while not bad, was already 50% at 15K miles, and this is with the regular shifter. Eventually as you wear down the synchro's the gears get worn as well (my 2nd had very minor signs of wear that without replacing the synchro in time would have caused issues. Things like heal and toeing and double clutching help tremendously in preventing wear when done properly. I replaced my synchro's with cup car steel synchros BTW.

Thank you Montoya, something I need to have checked out for sure.
You will get precision with both CAE and Numeric that's for sure. The centering spring is integral to the CAE shifter and requires extra effort to move out of the 3-4 gate which is a good thing. Other shifters including stock and Numeric rely on the centering springs in the transmission which are weaker. The stronger spring helps keep your movements more in line with the gates and prevent mis-shifts.

note the numeric offering can be set to standard, short or very short throw, I have mine in the standard position and don't see the need to go 'short'.
Missed gear changes will do more damage than a short shifter.

I believe the noise is because the cup cables have no rubber to absorb the noise from the transmission so the noise resonates and you hear it through the opening of where the cable go into the cabin. My mechanic said it is totally normal and means that the cables are doing their job. This has to be the best short shifter set-up that I ever experienced whether it was aftermarket ones for the E46 M3, E92 M3, and the 996TT.

Numeric shifter installed - wow it was waaaay easier than i expected. I think the hardest part was just the paranoia of removing the cf center console.
Stock unit is really beefy, but the nylon plastic absorbs all vibration and with it much of the tactile sensation. Can't wait for the numeric cables. having those added with some long tube headers i got from red bear by someone with more skill.
