Yeah, I guess my "PVC Rollcage" idea to get into the race group isn't such a good idea after all...
Note the bolt-in roll hoop (not full cage) punched through the floorboards. (Visible in pictures where care is pancaked)
This wreck happened at Hallet Circuit, in Jennings Oklahoma.
I've talked to a few drivers that are familiar with that track, and they believe that this happened as a result of the uphill Left-hander just before going into turn 8. Either going too fast, or braked over the crest of the hill, rearend got loose, carried left off of the track into the tire wall.
Apparently, this is a pretty common wreck at that track (minus the rollover carnage).

I found a video replay of the driver after he got out of the car:
