This is an interesting thread. I think if GM can flag your car, you should have a right to check and find out why.

If this guy got red flagged for running at the front of HPDE's then a lot of us will have the same concern. My car is bone stock. So is OP's. Wait...I take that back, I have BIG numbers on my door so it MUST be modified, right?

Still have not seen one car being denied warranty for track related activities.
