Probably because the Z/28 is to be a track day special, and rules have changed a bit.
I know for a fact that most coupes are not allowed to have i.e. a sunroof if you want to go racing with them...
Putting a T-top on a "closed track car" would entirely beat the purpose of said car and rule it out for any potential race series...
