A radial is hooked, or it's not. There is no in between regardless of the track.
As far as what street/strip car will bend a housing.........you would be surprised. MOST housings under even moderately powered cars are bent now. Don't believe it...........narrow a few with a jig and you will know. I could always tell when I bent my own........the car got harder to push than normal
