Not sure I get what you mean here. You can’t carry over an ESC tune from something like a GT3 to a GT4. You may be able to copy a reasonable amount from a GTS, but regardless, Bosch Engineering calibrate all the GT cars where as Bosch Chassis do the core vehicles.
THe esc system was from the RS, retuned ofcourse but a MASSIVE step up , the 981 Spyder and T models are NOT Gt cars or have Gt tech, they are base model cars with a few add ones, it’s worlds apart. Basic esc, basic brakes, fixed suspension, they are not In The same league as a GT4. Dynamically people who rave about the T and old Spyder don't have a scooby doo or maybe not tracked or owned a GT car, hence they are very over rated by owners who sadly don't know enough on how a GT car drives once you start to push.
Ok for every day use if you want a base model up 10% but nothing to write home about.
That’s why the new Spyder is a massive step up from the old car, and the GT4 is only really a sideways move up a few %
don’t compare T models and the 981 Spyder they are far lower down the chain as drivers cars.

Every 9X1 generation Porsche has a Bosch 9.1 modulator. The platform solution software is common across all cars and shares much in common with all vehicles (of other brands) that run Bosch 9.1 hardware/software. The core Bosch software team produce a software concept which has a base component that sits in a common piece of hardware, which in ESP premium, as found on 9X1 cars, is a 6 piston modulator.
Across all models (regardless of being a GT car or not) the software strategy for TCS, DSC and ABS is identical. The tuning is approached slightly different between the GT and core vehicles, but there is no change in software strategy. It’s just a difference in tuneable parameters. The ability to switch DSC off but leave TCS on is nothing more than a parameter change. You can select what you want left on or off during the calibration phase.
As I said previously, Bosch Engineering (who are a stand-alone department) do the calibration for the GT cars. They will almost certainly start with the DSC calibration for the core car and modify from their. I suspect most of the effort though goes into TCS calibration. Other than that, having driven both 981 S and GT4, I can’t honestly say there’s a great deal of difference (if any) in how the stability control is calibrated.

Not wanting to start an argument here, but I think you’re perhaps taking what’s written in the marketing blurb from Porsche as gospel.

All I know is to drive it’s night and day a 981 or GTS vs a GT4 or GT3 system. I owned all 3 at the same time. Every 9X1 generation Porsche has a Bosch 9.1 modulator.

The standard is for nanny noobs and far too restricted.
The GT4 and GT3 have 2 modes and are recalibrated to be more driver focus, less sensitive etcetc,
They maybe the same the unit, but you cannot do anything with it so you are stuck with nanny crap calibration on the T, GTS, Spyder etc.
You can also split tc and esc as you have two buttons over just a basic PSM button.
Just more work goes into Gt cars and track setups over the road going cars and for mr ave they won’t know any better owning a T or GTS.
I'm with R on this one. 60K for a nice 981 GT4 would make it the right value car imo. It would certainly get me eye as I was trying to buy one last Feb at circa 75K but a few slipped through my hands. Modding one makes it a really nice toy, after being in ChrisW's its a right animal. Also puts it in the market with the Exige 410 Sport which is currently dropping and in the mid 60's for a nice one. At the moment I'd go for a the 410 Sport, but if the GT4's dropped some more I'd probably swing towards the GT4.

and if you want 460BHP a remap gets you back the power, but the cars 1325kg with a real 410BHP anyway.

Drive a 991 back to back with a standard Carrera. In the nicest possible way, you’re wrong. Save that, to greater or lesser extent, all trim levels are pure marketing...
Can’t speak for the Boxster / Cayman versions though as I haven’t driven one.
the cayman t is just a certain spec of cayman with no pcm and fabric door pulleys lolCan’t speak for the Boxster / Cayman versions though as I haven’t driven one.
the 911 t is a base carrera with 4 wheel steering made availible as well as lightweight rear glass and rear seat removal, you could spec a t without them and it would literally be identical. the t was a marketing exercise
having been in stripped out cars (i.e the rear seat removal and thin glass letting in more sound), there is deffo a placebo effect of making it seem faster and more alive just from sound alone.

Been up since before Xmas . Have you had any serious interest in the car ?
This may sound strange, I could have sold it on 3 occasions, each time a buyer with the intent to buy it turned up, I suddenly had a change of heart, but now it’s definitely for sale!Edited by Fizzbomb on Wednesday 29th January 12:05
