Lift-off oversteer
Lift-off oversteer is the rear stepping out when you suddenly lift off the throttle mid-corner, as weight shifts forward off the rear tires.
Also called: trailing-throttle oversteer, lift oversteer
Lifting off the throttle works like a gentle brake: weight transfers toward the front. The front tires gain grip and the rears lose some. If you are cornering near the limit and lift abruptly, the rear can suddenly have less grip than it needs, its slip angle grows, and the back of the car starts to come around.
It is common in front-drive and mid-engine cars, and in any car that is set up loose. It usually appears when a driver enters too fast, panics and snaps off the throttle mid-corner, or lifts on a fast sweeper because of a scare.
The best cure is prevention: get speed right before turn-in, and if you must slow mid-corner, ease off gradually. If the rear does step out, look where you want to go and steer smoothly in that direction. Re-applying a little throttle can help settle some cars, especially front-drivers, but be careful in powerful rear-drive cars. If the slide is beyond saving, use the spin procedure: both feet in.
Abrupt lifts are a leading cause of spins in fast corners; smooth throttle management keeps the car balanced.
The rear tires run out of grip first. The car rotates more than you asked. Look where you want to go, steer smoothly into the slide and avoid sudden lifts or stabs of the brake.
