Once they got the right tires in and swapped out, everything felt normal.
Good luck.

How in the hell does a shop make this mistake. Don't ever go to that shop again lol.
@OP the problem you are describing does indeed sound a bit more sinister than simply a bad alignment, your current alignment isn't track day tweaked and tuned, but it should do fine for 45 miles per hour.
I suspect something like a cracked/broken bushing or maybe even a loose control arm/midlink that is allowing the wheel to steer on its own. Do you hear any vibration noise like it could be a wheel? Something is very not correct and you should take it to a real Nissan/alignment shop.
@Rusty, I have taken temps at track for last few months at -2.0 rear camber, and there is no reason to run that much. I will probably bring it back down to about a -1.6 to -1.7. Even for a full track spec running slicks I doubt you would ever need more than -2.0 if you are sprung decently in the rear.
Thanks for the pointer on rear toe as well, I have been having snap oversteer issues for months and will definitely try your suggestion of adding just a tad of toe in, do you suggest like .10?
