Roadster is a porky girl, not nearly as nimble as the coupe in that environment. Some (most?) won't allow running it either as you are not going to be getting a role cage in there, and the integrated roll hoops if allowed, may need to pass the broom stick test.
I doubt I could pass the test with a helmet on being 6'. If the driver education group allows for the hoops as is, I certainly would toss it around regardless. Fun is fun.
