BEFORE VS AFTER AN ANTI-ROLL BAR

BEFORE

When cornering a turn, the transfer of weight will make the car sway to one side, causing body roll and difficulty turning, weakening the steering response.

AFTER

The upgraded version of Ultra Racing’s anti-roll bar will be more effective in preventing the car from swaying through corners, greatly reducing body roll and enhancing stability/handling.

UNDER-STEER

Under-steer is a condition where, while cornering a turn, the front tires begin to slip. With the front tires broken loose from the road and the rear tires continuing to grip, the vehicle will ultimately turn less than desired. 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 turn. The dangers of under-steer lead to your vehicle running off the road, possibly hitting obstacles or other vehicles. Under-steer occurs in front-wheel-drive vehicles more often than in rear-wheel-drive vehicles.

 Car manufacturers employ the FF (front-engine, front-wheel-drive) setup in modern cars for improving driver and passenger safety. The natural behavior of an FF car causes it to have inevitable under-steer due to its heavier front end. Under-steer can be corrected by stiffening the rear end of the vehicle by adding a rear strut bar and a rear anti-roll bar. 

OVER-STEER

Over-steer is the direct opposite of under-steer. The front tires continue to grip the road and complete the turn while the rear tires break loose. This causes the rear of the vehicle to kick out, turning the front of the vehicle into the turn even further.  Over-steer occurs in rear-wheel-drive vehicles more often than front-wheel-drive vehicles. Sometimes over-steer is done purposefully, which is called "drifting".

FR (front-engine, rear-wheel-drive) or RR (rear-engine, rear-wheel-drive) cars mostly experience over-steer when cornering. Over-steer can be corrected by stiffening the front end of the vehicle by adding a front strut bar and front anti-roll bar.
