For what its worth I highly doubt that many drivers really zero in on the chassis being defined by the name of the class. I think most drivers pick cars three ways, what they have in the driveway already and tune on, what they think will win or what they think is cool and fun. Touring, sports or GT - i bet many folks would have tough time defining these chassis (lol - like a bunch of folks on this thread bahaha!)

Narrowing a class to fit a chassis definition is a loser business model.
