I am with everyone that says the Hellcat is a track worthy car. The Demon, probably not so much. Even in the advertising they advertise it as purely a straight line car. The suspension is totally different than the Hellcat and is not meant to handle well.
First article I could find that talks about the suspension. I think I would not want to be on a track with a car that in essense drains the front shocks of their fluid anytime you go full throttle. This is how they got the thing to get that track time. Crazy weight transfer to the rear under throttle.
