Does switching PSM off on the 997 assist with understeer particularly on the track?


In a word NO

If you are experiencing alot of understeer most likely you are overdriving the car. If the car is not turning the reaction that most do is to turn the wheel more...which is the wrong correction.

Leave PSM on, its parameters are quite wide.

Do yourself a favor and attend a high performance driving school (PSDS) to better learn vehicle dynamics and car control. Money well spent!
