ABS can't be switched off on 991.2 GT3???

I'm willing to sympathize with your apparent dismay at not being able to disengage ABS however I'm curious what aspect of your learned braking 'technique' is hindered by ABS? As far as I know (and I might be wrong), threshold braking is the primary braking 'skill' to master in non-ABS cars with trail-braking being a natural follow-on skill to acquire. If I may ask, why can't you simply continue applying your learned non-ABS braking skills in an ABS equipped car? If threshold braking, you can still do that in an ABS equipped car...the only difference being that if you mash too hard, the ABS kicks in telling you that you did it wrong. So if you do it correctly, (as your skill suggests) the ABS in your new GT3T should never activate and you get a similar experience as a non-ABS brake feel. Am I missing something?

The $2,000 sets of tires wear out quickly enough without the risk of flat-spotting them

Well, if you want the fastest car on track, it won't be the GT3 touring. Go ahead and let me take it off your hands. LOL. Fact is, there is always a faster car out there. And a street car is not a race car. Not a lot of Formula 1 cars driving to the track. So, compromises are expected with the car you are choosing. And remember, you are on street rubber, not slicks. Besides.......unless truly doing time trials or racing in a club race......It is really you against yourself. You know there are also crappy airbags too these days. And rear wheel steering. And PSM. And catalytic converters. If looking for a pure race car driving experience, maybe look for a car without RWS? No racing series allows that driver aid. All kidding aside, the GT3 touring will be a great car. If you haven't driven a car in 20 years, you should be amazed at the speeds the typical sports car now attains.....without a full cage!!

and I owned one : a new 1986 Audi 5000 CS Turbo Quattro Sedan ..the " wonkiest car in the world " at the time , by far , with full time AWD , and three avail diff lock choices via a rotary switch on ctr console. ABS could be turned off by a button above the radio ..but why ?Because computing power then was not good enuf to prevent ABS enabled cars to suffer almost an inabilty to stop in " pebbly " snow from even moderate speeds , so turning it off allowed it to lock the wheels and form a wedge of snow to stop . ABS came to US cars around 1985 and my 85 first gen ABS equiped MBZ was sometimes unstoppable in the Chicago snow while the Audi could do so ... provided you turned it off . It was also sold ONLY as a MT , no Automatic ..:can you imagine any manuf today prod its flagship luxury sedan MT only ?

Having tracked a fair bit I can't see the issue with ABS as it does come in very late on GT3 so essentially without ABS you would tell yourself off for wheel locking ... with ABS you tell yourself off for the ABS coming in...
Very obvious either way if you mucked the braking up and the ABS does not get in the way?!!

cup cars do not come with ABS and therefore destroy a lot of tires during the adjustment process. of course customers tend to destroy cars when they get it wrong also.
the reason cup cars can manage without ABS...adjustable brake bias. so you can manually, while on the straightaway, adjust more rear or front depending on which type of feel you want. The more front you dial in, the more lockup will occur which is really counterintuitive but that's reality.
Also- OP: you cannot threshold brake and have microlocking on regular *** tires. that only works on slicks or in the dirt in a modern car.

I agree with OP, and think ABS is one of the biggest driver aids going, and wish it could be switched off.
Aside from detracting from track skill, road cars with permanent ABS are a disaster in the snow, IMO.
and as I said earlier, you won't be going really fast In a modern GT unless you are using ABS deliberately. You're doing it wrongly (or slowly) if ABS doesn't kick in.

You/we are missing cadence braking in extremis.

the rear engine
The huge rear tires
The weight in the rear of the car
If you drive at 50/50 split F/R you will flat spot cup car tires all the time. You need rear braking to help rotate car otherwise it's understeering too often.
Leh Keen was apparently the best at dialing huge rear bias to get what he wanted.
I think the max I was able to corral the car with was around 54-55% rear bias.
In the wet- with no abs- we run a lot of rear brake and use the downshifts to really manage the deceleration. Gets fun really quick.
