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.

This really sucks big time. Can a fuse be pulled to disable it? If so anyone have any experience with this in a GT car?

Again sorry for being late to the game here, but this is super important to me.
Also, did you know that the did away with carburetors and now have this weird thing called "fuel injection".. it's crazy.. CRAZY!

I found this online to improve the abs. Will it work on the 991.2?

OP, why not simply learn to drive a modern high performance car or conversely, you can look to buy a non-ABS Carrera 3.2 or buy an early model 964 and go full track prep.

You might want to check out the Glickenhaus SCG 004S https://www.carmagazine.co.uk/car-ne...res-and-specs/

If you look to the right of the steering wheel you can see a ON/OFF switch for the ABS

Just make sure you let everyone else know what set-up you are running (ABS-less) on track days.

... so everyone can give you 300m buffer...

Having steering wheel working the opposite way is also challenging! I tried that on a bicycle. Was even offered 100$ if I can go 5 meters :-) (but paid 20 to take that offer).

I remember during drift-days that at some cars when you are spinning - the brake pedal is stiff (no braking - even if you press the pedal maximum). Meaning no braking possible based on electronics - during reverse sliding or / spinning. This can cause problems.
Don´t know how it works with the 991 - as long i never spun one.

Luckily you CAN pay to see that in the various IMSA series and the Porsche GT3 Cup.

CUP yes, RWS street cars would need mechanical diff, you have already if you have a manual, get rid of RWS and brake bias.
Why get a 991, I just wonder.

Great to see the return of the gated manual. Been missing that since the Lambo and Audi V10's banished it a few years ago. If Ferrari were to re-introduce it (gone much longer), imagine the waiting list...

Lifelong Porsche fan. Last car (of any type) I *owned* was a 964 back in the day. Finally in a domestic situation/location where I can splash out on ONE car. To me the appeal with the GT3 was that it was a road car with some racecar character, and closer in spirit to older 911s. Drivable to the track and also capable/competent when there - means I don't have to buy a Radical and store or haul the thing and maintain it. The GT3 Touring which I'm due to collect next week was a really nice compromise on all those things. It's just now a lot more of a compromise than I expected or wanted. I realize it's my own ignorance for just blindly assuming that all these cars would come with an ABS-off button.

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?


Quick Reply: ABS can't be switched off on 991.2 GT3???
