Up to 66 failures now I see, with pretty much weekly new additions to the list:

All the same issue, 3rd gear lets go. It's clearly not up to the job, but the replacement gearboxes don't seem to be much better.

Thanks. I'll dig into those threads. My 987.2 is not a GT4, that said, it does have an auxiliary cooler and pump on the trans, which I run when tracking....

Find one with a rollbar, 5-6 point harnesses, fire extinguisher, possible some bushings and track alignment parts installed, 3 sets of wheels.
I drove my 987.1S for 5 years, street/track and to its last day it was fun, miss it.

987.2 manual uses the same transmission, just different casing to connect to the 9A1 instead of the M96/M97.
Florida weather and Sebring are a test for endurance.
If your Cayman manual trannies are reliable, they are either modified (extra cooling), running in cold weather, driven in slow motion or a combination of these.
My Spec Boxster went through 3 transmissions. Non of my GT3 have asked for transmission replacement, just LSD refreshes. My PDK cars have been solid in the same weather where Cayman/Boxster broke, and they are running heavier cars and more powerful too, so they get stressed even more.
No offense either, but your mileage may vary.

I travel the USA and do about 8-9 race weekend per year. Never had issues and my trans has 60000 miles(not all track miles) . I do run a cooler and lsd and flush every 2-3 races.
I run the car hard, watch my videos.
Pdk trans go in limp mode, failed, bring up some coding, stuck in reverse...

If you're already concerned about the cost of a GT4, you shouldn't be tracking it. Rule of thumb is don't track something you can't be afraid to crash.
Further- it is still set up as a street car. It's fantastic, but comes with compromises that people above have modified for track use. And at the end of the day it will still be a jack of all trades/master of none. Spending tons of money to do HPDE's is silly. Get a built 987.x, M3, or something similar and dial it in for half the price or just get a cup car and race it. I promise you will have more fun/less stress that way. Chasing lap times in a non-competitive environment is worthless in comparison to improving your skills and just getting seat time. Everyone either grows out of it or gets sick of spending money to be a big fish in a little pond!

Everyone should know what they can comfortably afford to track and no amount of HPDE Insurance will bring back that equity if you pile up a car you own money on.
I also suspect that just like the regular car insurance market -- it won't be long before the leasing companies start bringing down the hammer on folks who pile up a leased car on a race track... share in the loss so to speak, when it's time to auction off the car. I know if I owned a leasing company, I'd have exclusions on tracking a leased car.

While I agree with the sentiment, "You shouldn't be tracking what you can't afford to crash" - that's what DE insurance is for. I have a good friend who wadded up her car at a DE, used Lockton, and the claim was paid, no problem.
DE insurance might not heal the emotional damage of wadding up a car... but it should cure most of the financial (minus the deductible of course).
The challenge with tracking a car you can't afford to crash is, IMO, it alters your decision making in the event of an about-to-happen "oh ****" moment. If you only have Option A and Option B, both of which involve hitting something... you may try for unavailable Option C "hit nothing" and ultimately make the situation significantly worse. Seen it happen MANY times with folks in the 2-wheeled world at track events.

I think it comes down to what your goal with the 40+ track days is. If you're just going out there to have a blast and improve yourself as a driver there's really no need for a 981 or a GT4. A 987.2 would be more than capable and keep consumables/crash costs down as well.

Id get a 987.2 and build off of that.
The problem with the gt4 is that you really damage the value by doing mods to it that permanently alter it. The biggest thing being the fenders which you need to mod to get more rubber down.
Out of the box the gt4 is really limited in terms of tire options and wheel sizes - which really determine how fast the car can be.
Id get a 987.2, throw an SPG or RSG recaro in it, toss a better fixed GT wing, square 18x10.5 with 275 or 285 whichever is more common for EHPs. KW clubsports or bilstein clubsports so that it is tolerable to drive on streets. Find some blank rotors and fill up DTC 60 pads. That should be more than enough to keep up with a GT4.
