Neutralize UNDERSTEER. The front wheels are likely to slip towards outside of the turn angle, driver can solve it by turning a little more slightly but the handling is reduced, vehicle’s behavior is less predictable and tires are likely to worn out faster. Understeer often occurs in front wheel drive layout vehicles. As most modern cars go, car manufacturers employ the FF (Front engine, Front wheel drive) setup for improving driver and passenger safety. The natural behavior of an FF car is to have a slight understeer, due to its heavier front end. Understeer happens when the front wheels lose their traction and won’t turn any sharper, even when the steering is being corrected to turn the car more. This will cause the car to go wide instead of following the line. Understeer can be corrected by stiffening the rear end of the vehicle by adding a Rear Strut Bar and a Rear Anti Roll Bar.

The forces acting on the car Chevrolet Sonic T-300 1.4 (2011) when cornering. Front and back view.

When any of the wheels loses contact with the road surface, there will be a deviate in handling; each of the suspension system should keep all wheels on the road surface in spite of hard cornering and in change of steering position. It’s always pleasing that that car can be set for a tiny amount of understeer so that it responds predictably to a turn of a steering wheel and the rear wheels to have a smaller dip angle than the front wheels. However this may not be achievable at all times due to the vehicle load, road condition, weather, speed and this consumes excessive time for the driver to adopt.
