I haven't experienced the unpredictability first hand and I really don't want to. I appreciate your concern and will certainly keep my eyes wide open!

A properly set up Cobra will not have excess TTO, shock valving, ride height, spring rates, rake angle, rear camber (assuming an independent rear) and even front to rear sway bar ratios can effect the tendency to come around on throttle lift.

You can use the this trait to get the car into a corner apex by alternately lifting and applying throttle (small amounts) until you get the proper angle. When you lift the nose comes in, when you apply throttle it moves out but not in an uncontrolled fashion. The cars that snap over steer under TTO usually have high ride height, too much rake, not enough rear camber and front to rear wheel rates that promote this problem. As pointed out many times within this thread though, the driver can be the major problem especially if he or she panics and brakes when the tail come out after a throttle lift. It is against everything you have ever been told but the throttle is your friend and will help control the car if you get back into it smoothly and slowly.
