My 991.1 GT3RS has a bad case of understeer and at the AX today it seem to really slow me down.
Currently have a full track alignment, and corner balancing.
Currently the back sway bars are at the softest position, and the fronts in stock position.
I originally had them set to this before going to California Speedway because the last thing i wanted was to have overstreer going through the roval at 140+, but I left them at that position and I am thinking they need to be changed.
Wondering if any other GT3RS owners have played with the sway bar settings and what they found their experience to be.
I have rear full stiff and front either medium or full soft.
If on Cup2, once they are heat cycled (say 3 to 4 track days) they still have profile but little grip, which manifests itself the most at the front, i.e understeer.
I can understand you want to avoid oversteer, as the RS can be snappy, but the car does handle better with ESC off. I could not say this reduces understeer per se, but it's worth trying.

You have rear wheels stiff even for big tracks, or just for AX?

ESC off and TC on?
I am based in Europe, so not sure what AX is.. but yes, I have rears always on stiff (mostly drive at Spa). I did it initially to reduce wheels touching arches and rolling over edges (latter just reduced, but still an issue without a clear solution). Overall I find it makes the car more predictable in its handling though. It does oversteer, but with the rears stiff, it doesn't seem to load up and release as much as before.
ESC off and TC on is a good setting. Bit of a safety net for power oversteer but more natural overall handling.

AX=Autocross, smaller course with tighter turns then your traditional bigger tracks.
I switched the fronts to soft today so now I will be rear middle, and fronts soft.
Have an AX set up for the Sunday after next so we will see if this helps but on a bigger and faster track like the one I am going to in late Sept at Willow Springs, not sure I would want the fronts soft for that since we will be hitting speeds of 150+ in a couple areas.
Thanks for the explanation. Personally, on very tight corners and lower speeds I would go soft front and stiff rear and TC/ESC off so you can set the back and get the car straight more easily.
Have fun! I am off to Spa tomorrow, but weather not looking great.
