Have any of you Corvette owners found any evidence that the C8/Z06’s has an integrated roll bar like earlier series have to avoid or waive adding a roll bar for Grand Touring Division?
The Race Director (Frank) needs evidence to waive the roll bar rule and can not find it.

Here’s the answer on Roll over protection on the C8 noted in GM Authority that similar to the C7 the A pillars on a C8 can withstand 2.25 times the weight of the C8. Also confirmed on the Corvette Forum. 
NOTE: GM provided position to NASA (North American Racing Association on the C8 like they had on earlier models noting the B piller is also on a hoop.
My typo above…NASA is National Auto Sports Association based in Las Vegas and is sanctioning body for a large number of endurance race events.
