ESP is off off?
I would not turn it off, great safety factor. However on my corvette to turn it off if the car is moving and you turn it off only active handling is turned off. To turn off traction control and active handling the car must be at a full stop. So my suggestion is to insure you are full stop. I would also check the owners manual,, gear selection might also be a factor. But why turn it off. I was driving on 2 lane rain soaked highway 4 AM and started to pass a car doing 30 mph. When I stepped on the gas the vet had so much power the rear broke loose. The computer took over and in microseconds the car straightened up and passed. If the computer were off I would have been in a ditch. However if you are on the drag strip you might want it off.
