I have never driven a T but wondering how different it is from a Base as far as performance? I know the T is lighter but don't think 40lbs is very significant. Does the different differential make a big difference? I think acceleration is pretty much the same as is braking. Is it handling where the difference is?

It’s the sum of the parts… It might not be too much lighter (depending on your spec), but it definitely feels lighter (due to the suspension and spring rates), the acceleration feels quicker (due to the reduced gearing and more low down torque), and the steering has some tweaks too (especially if you have RAS and thanks to PTV and the mLSD in the MT). They changed the aero a bit from the Base, and then there is the increased engine presence in the green house (due to less sound deadening). Some Other Ranks enlisted in the T Army may also have views…

You can also do yourself a favor and search out Stout and his views, both here and in his mag, that provides an excellent breakdown of he and his running buddy’s views based on some extensive wheel time in both cars….

Good luck!

Is the gearing different in PDK and manual cars?

S S

The final drive ratio on the 991.2 T is 3.59, same as used in the S and GTS models. The Base uses 3.44. Separately, you lose ALL LSD (not even PTV+) in the PDK T, whereas the MT has the mLSD.

We discussed this pretty extensively back in 2017-18 during the launch and initial run-up. I found an old post of mine from Dec '18 (in this thread: https://rennlist.com/forums/991/1120...he-dyno-3.html ) with these figures:

991.2
Ratio - Manual / PDK
1st - 3.91 / 3.91
2nd - 2.29 / 2.29
3rd - 1.58 / 1.58
4th - 1.18 / 1.18
5th - 0.94 / 0.94
6th - 0.79 / 0.79
7th - 0.62 / 0.62
Reverse - 3.55 / 3.55
Final Drive (Base) - 3.44:1
Final Drive (T, S, GTS) - 3.59:1

OP, I would not discount the base 991.2. The performance is slightly better out of the box with the T, but most will tune or modify anyways for the track if top performance is a priority. In the street, the base might be a better ride and 9/10 of the performance. I love my base 991.2 and I have already added a sharkworks exhaust, AP Radi-Cal competition brakes, and soon going back to 19 inch wheels. I will likely have a LSD added here soon too. At that point, I will not have rear axle steer, but I am not too concerned about that. I have a 7 speed manual, so I am already passing on the performance of the PDK.

This is a fun review of the base…

How much would an LSD cost? I'm in the same boat, love my base 991.2: Softronic Tune, SOUL Headers & Sport Cats, Numeric shifter & cables, DSC, car is fantastic. The more I track it, the more I'd like a LSD.
Thanks

Prohibitively expensive to retrofit an OEM one, I'd assume.

I think @4 Point 0 put a OS Giken or Wavetrac or something in his. Not a cheap option, either.

Everything above… i remember driving a base and thinking it was great so I knew the T would be atleast the same.

when I drove my T the first time I didn’t understand all the noise all around me. I thought something was loose or not removed during delivery. I was hearing all the little road pebbles hitting the car, since the T has reduced sound deadening. It was like some sort of asmr experience.
…..oh that & all the rumored special 🧚‍♀️ dust porsche applied.

How will you be using the car? The capability of a driver is so much more important than the car...at least when looking at a base vs T.

The last I read was that a mechanical diff was not available for the base. Would be interesting to see if that has since changed.

The T gives you driving performance capabilities simply not available in the base. I have an S but would have been equally happy with a T with the added coolness value of its unique specs. A nicely optioned T will likely hold its value better than a comparably spec’d S.

I’ve owned many Porsches and just purchased a 19’ T from a RL member, and I cannot stop driving it. It feels nothing like a base 991.2, IMO. For my purposes (backroads, early morning jaunts, taking kids to school) it is perfect. The 7 speed manual is where it’s at, skip the PDK.

Yup! 000 magazine issue 6 has in in-depth Carrera T review with Stout's own 991 base as a point of comparison. TL/DR the T is an amazing package but a base 991.2 owner probably doesn't need to upgrade (and that's just stock-for-stock of course, as noted in this thread some judicious mods can close the gap so long as RAS isn't a must for you).

4 Point 0

Yes, I had an OS Giken mechanical diff modified for my GTS. The E-Diff would give up at the track.

The biggest difference with the mechanical diff was in the braking zone. The car no longer dances around under extreme braking. It hunkers down and brakes straight.

The rest of the time it is seamless and feels stock.

Well worth the price of entry.

Is the LSD a 1.5 or 2 way? LSD is definitely in my future.
