Quite a few references I've found, have the Roadster a tenth or two faster than the Coupe, on accelleration of the line. 
I Guess it might have slightly better traction with weight tranferal to the rear axel when you drive it like a road tester. 
Plus with the top down, (as it should always be) 
the c of g must be a little further back & lower. But who the hell drives their own car like that. So in the real world there rely is nothing in it.
