The body is just another factor in the overall setup of the car. Like all items in your setup, you use the environment to pick out what to change. Temperature, Surface, Traction, Tires, all have bearing on which body performs better.
niznai , for any given setup, run different body's back to back, and you will tell how much different ( or not ) they are. I can guarantee running a R9R back to back with a Mazda 6, you will know.
