What caused this spin?

The car is a 997 GT3 running in the black group at Summit Point on the OEM special MPSCs. Conditions are clear, but cold. I found good grip with my Toyo RA-1s, but I was not driving as fast.

No speakers here at work but he/she was 4 ft from the apex and probably pinched the turn and/or lifted. I'll check it out again at home with sound if there are any other clues

oooohhhhh that's scary #9. Gotta get that one right.

Looks like maybe that dip right at the apex unsettled the car. I've never had a problem with it, but I've heard it can get you if the car isn't positioned right.

Just my lowly opinion.

Sounds to me like he got on the throttle too early....

My assessment is more in line with Tony.  I feel that the driver apexed too early, which runs you through a larger mid-corner bump and probably didn't unwind the wheel as they picked up the accelerator.  The track has a few undulations after that which can also cause the back to step out if you are trying to "hold the wheel".  It would have been nice to see their hands.

One thing that I can say for certain is that the driver was way over their head.  That was a silly place to spin, no where near trackout, and they did not react at all to the slide.  Once the car started coming around, there was no change in the yaw at all.  It looked like once they finally realized that they were spinning, they just locked up the brakes.  IMHO, for a black group driver that should have been a little bobble, and on their merry way, not a spin into the tires.

Did you happen to see the car after the incident?  How bad was it?  Looks like a pretty good hit.

I was in the carousel when the plume of dust rose. Took the flaggers a long time to get the black flag out.

The car backed into the tire wall, shattering the left rear bumper. The damage just looked to be cosmetic, though, and the driver taped it up and ran the next session.

Judging from the video only (and that's all we have), I think he did not track out all the way and got on the throttle too hard for his steering wheel position. I wish we could see his hands in the video.

This wasn't the Dentist (and his wife drives in white) with the French accent was it?  He's a pretty good guy.  I guess it's unfortunate no matter who it is.

I am glad to hear the driver wasn't hurt.  I am always upset when I see someone crash.  I was wondering what you thought Larry.  I was thinking the same.  I wonder why the driver seemingly did nothing to correct the situation?

Marty, it is Stephan who is French. Astrid, his wife, drives too. I didn't know he was a dentist. Nice guy and good attitude about pranging his car.
