"LSD Settings:
Initial - Increasing this increases the response of the LSD - it makes the car a lot more stable on the straights, but, by limiting the slip on the outside wheel, can make the car more difficult to turn. Higher settings will make front-drive cars understeer and rear-drive cars oversteer.
Acceleration - Increasing this increases the effect of the LSD during acceleration - the higher the setting the straighter the wheels will try to be on acceleration. This will cause the car to understeer during acceleration if front-drive and oversteer during acceleration if rear-drive.
Deceleration - Increasing this increase the effect of the LSD during deceleration -the higher the setting the straighter the wheels will try to be on braking. High front settings will cause oversteer, and high rear settings will cause understeer."
