alignment
I am amongst those whose RS will spend most of it's miles on the track, but still want it to be a bit road friendly.
Being in the Northeast, I have only had one track day in the car, but will be back at NJMSP/Lightning this Sunday/Monday, so I will gain some good shakedown time in the car.
On my first track day in the car, I was on an unfamiliar track (Thunderbolt) and the car was stock other than RE10 pads, AP racing rotors and Motul fluid. I ran the MPSC2s at 32/35 hot and they seemed pretty good (still long for R7s that will fit our cars in a 19/20 config).
My initial impressions of the car with stock suspension config are that it turns in very well and is agile, but was less straight-line stable during high speed braking than I thought it would be and didn't hold as many butt G's as I thought it could in a long slow turn (it was cold), but I think suspension tuning will improve both of these aspects.
I do have measured stock alignment (factory pre any adjustments) and will post those for reference. This weekend, I will take hot tire temps outside, middle, inside and post and may play with sways, trying stiff front medium rear and visa versa and post, depending on how it under/oversteers. All of this is of course weather dependent.
I don't think I will have enough track time to play with aero wing adjs.

I started with camber at F-2.2 / R-1.9. Tracked it 3 days, 3 tracks. The rear outside shoulders are getting killed. Fronts weren't horrible.
Taking it to F-3.0 / R-3.0 and will report back. Honestly looks like the car would prefer more in the rear. Still a streeter for me, so have to find a hybrid setup I can live with.

My car is done by the Black Falcon race team in Nürburg. They were running an RS during their winter events at Ascari and Portimao and had issues with rubbing when going over 2.20 (~2.3) on the rear. Since this is too little to accomplish even wear it is very interesting that you went higher, presumably without issues or adjustment to the arches?

And don't forget, you have a differential rubber tire if running MPSC2. The inside 3/4 is a harder compound than the outer 1/4. SO, by design, they will wear like that. Many in the GT3 world kept increasing camber, but didn't get faster, and the tires heat cycle out before the outer shoulder was gone. And when they move back to stock, they claim better drivability, and same or faster lap times.

Some excellent info in the place!
Will talk to my mechanic and see what he thinks is possible. Will first of all try different variations with ARB, as generally full stiff on the rear seems to be the way to go.

I run the "normal rubber" Dunlops now and the rear tires wear evenly. I haven't checked temps but once I go back to MPSC2 the outsides should still cord first due to the type of rubber on the outer edge but I think this means the tire is used pretty evenly. Sorry, no temps across the thread.

Right, 997's corded on the inside, this is a whole new game.
I've done it often, but you shouldn't drive on corded tires. Those spots will grow quickly.
In the grand scheme of things tires are cheap, you'll feel more confident with new tires, so you will go faster and you don't risk a blow out or running out of tire before the day is over.
I've had a tire blown at 135MPH and hit a concrete wall at Road Atlanta. Caged racecar, had it been in my RS it could have been Game Over. I wasn't even sore the next day but I was already envisioning white coats standing over my on my way to the wall..
I drove Daytona at 170+MPH only to see giant cords when I came into the pit. I'm an idiot.
