Here's a good example. Take a new ZR1 and "Jackass". They have identical engines, wheels/tires/brakes. Put Mark in both cars and he'll be much faster on the track in the new ZR1.

I don't disagree...but the Vette is a two seater. Let the two seaters run with the two seaters.
I see no reason to put my car on 275s in a different class than a 1969 Camaro on 275s. And a 1985 Fox Body on 315s should be in a class with a 1967 Camaro on 315s.
Weight limits and full interior restrictions can also come into play, but most guys with muscle cars on 275s are going to be the same guys that won't cut their fenders for wider tires nor strip their interiors for weight savings.
