I would say from my own personal experience Panteras do not like decreasing radius turns at speed. You have to decrease speed as the radius decreases. If you don't it will break away at some point. Many tires don't give you a lot of brake away warning. You should be running at least 35 psi. I start at 40 and work down. I can tell you that mine haven't been worked down at all from 40.
The secret is to drive the car like you are driving in snow...smooth. Steer and brake it with the throttle. If you stomp on the go or the stop, it doesn't like that.
I don't really think it is a fault of the car though. The Pantera is a very stable car at all speeds. Like small aircraft crashes these things are always put down to driver/pilot error. Other then that and maybe an oiled down road (
). Yep, been there done that. (my own oil too...don't ask!)Accentuate the positives. Your ok, no one else is hurt and the car is repairable.
