Updating this thread regarding repairs for my car.
The car spun off the track on 6/3 and my appointment at Tesla was set for 6/15. I got the car there for the appointment and after a few days the final diagnostics were to replace the following:
-Rear RH lower control arm
-Driven hub
-RR damper assembly (rev D, so correct for my 21)
-Aero shield-Mid
Including diagnostics and alignment, the total was just under $1,300 and repairs were completed today, 6/20.
I took the Martian wheels to Discount Tire to have them take a look, and to my surprise they said all 4 tires were OK. The rear passenger wheel got bent up a bit so they suggested that I get a new one rather than try to repair it.
So including the wheel and towing, my track spin-out cost me around $2,400, which is less than what I was bracing for.
Hopefully the car will operate without further issues and that I've learned my lesson so it won't happen again.
