How to ENABLE flipping with the CarController from Standard Assets

Hey all,
I previously used a different vehicle plugin that is now deprecated, like most of the stuff I’ve bought over the years… I’ve got a loop on my track and I’m using the new CarController but it’s stopping the car from going upside down, effectively breaking the loops.

I can’t see any code in the CarController that is stopping the flipping, anyone know how I can enable the car to be upside down? It just stays Verticle, basically the X rotation can’t go beyond 90 degree’s, looks stupid too.

Thanks for your time.

Nobody have experience with this?
