Anybody have the factory alignment specifications for a GTS?

I can’t find them anywhere I have them for my Gt3.
I checked the camber last night.
The rears were -1.8&1.9 the front was .9.
I want to see what the factory settings are.
I’ll probably increase the front camber to 1.5 with about 1/64 of toe
The car steers great, but I would like to sharpen it up a little.

Old thread and I think you got what you needed, but for what it's worth my GTS came from the factory at about 1.2°F and 2.1°R camber. 2mm rear toe in, 0.5mm front toe in. This was measured after like 6k miles though, so take it with a grain of salt.
I've shared my autocross specs here before: max front camber (~1.8 on my car), 2° rear, 1.5mm toe out front, 0 toe rear. Very sharp, but balanced and mostly well behaved for daily use. At high speeds under heavy braking it can pull a little aggressively to one side on bad pavement though. I'd probably add 0.5mm rear toe in and reduce to 1mm (or slightly less) front toe out for track duty, but I think the toe out is pretty important - with my previous specs (around 0 front), autocross was painfully understeery.

pretty much the same settings as my Gt3 that came from the factory with -1.51.6 on all four wheels.
reset the front toe on the Gt3 to 1/32 and it was towed out from the factory.
both cars drive great Gt3 feels much more nimble with basically the same alignment settings.
Gt3 has rear wheel steering the GTS does not both are manuals.

I ended up with -1.5 in both of the fronts 1.8 and 1.9 in the rear 8th inch of total rear toe 1/32 of toe in for the front.

Do you need to add aftermarket parts (arms, camber plates, shims) to get more camber up front on the GTS?

Thanks for the information. I also have RAS, but forget to mention it’s a 4GTS. My current settings are : LF -1.0 RF -0.9 TFT 0.03 RL and RR - 1.7 TRT 0.34. I’m leaning toward having the front alignment adjust only since my rear is close to what you have. Any issues with abnormal tire wear with your settings in the front tires ?
doesn’t seem to affect tire wear where you’ll really notice it if you start pushing -2 .
when you do align rear wheel steering you have to have the key turned on that centers the rear wheels
on both my GTS in my Gt3 I didn’t have to screw with the back
Luckily the rears were pretty good and the toe was even on both sides.
which to me is one of the more important things to keep the car going straight under power

I don’t think you’re gonna be able to get 1.8 without camber plates
the Gt3 I think you can get probably close to 2° without doing shims.
