I would bet the Miata is WAY more prone to flipage compared to the track width of the Vette. My rear tires were 315/40-17's, quite a bit of contact patch with a 10" wide wheel. Plus the CG is a bit better. One reason the Miata is so good at auto-x is the turning radius is crazy tight compared to the sh!t radius of the Vette. Get the Vette on a road course and forget about it.
Seems you might be overcompensating for more than just driving skills.
Braaaaap!
<edit> Not to mention me and a big friend could flip a Miata in a parking lot.
