When a vehicle—especially a large vehicle like a truck or motor coach—turns, force is distributed to the outside if you were turning right, force and weight would be naturally shifted to the left.
This typically causes the outside tire to lift higher than the inside tire. But, with a sway bar, tires are brought back to the same level, thus leveling the entire vehicle. On the flip side, if both tires hit something at the same force, there would be no need for a sway bar because there would be no twisting motion. Aside from safety, sway bars help prevent lopsided wheel alignment and work to maintain an overall better grip on the road.
The easiest way to determine if you need a new sway bar would be by taking your vehicle to a certified mechanic. So a car with a stiff sway bar that hits such a bump will either feel stiffer as if it had very stiff springs on the side with the bump, will lift the tire off the road on the other side, or both. Vehicles that encounter high turning forces and in which maximizing tire grip is critical, but that tend to be driven on smooth roads, tend to use large, strong sway bars.
High-powered cars like the Ford Mustang are often equipped with thick front and rear sway bars, and even thicker and stiffer bars are available on the aftermarket. On the other hand, off-road vehicles like the Jeep Wrangler, which need to be able to negotiate large bumps, have less rigid sway bars and dedicated off-roaders sometimes remove their bars entirely.
The Mustang feels solid on the track and the Jeep stays poised in rough terrain, but have them change places and neither performs as well: the Mustang feels much too rough over rocky terrain while the Jeep rolls easily when turned hard.

For instance, Toyota offers a TRD sway bar for the Polyurethane is a stiffer material, which will eliminate excessive flex in your suspension and steering. However, some of these bushings may need to be greased periodically. You can also fit your car with a strut tower brace. Similar to the anti-roll bar, strut tower braces connect opposite wheels via the suspension. However, the strut tower brace installs on top of the suspension, via the strut towers.
This prevents excessive flex, especially as the parts age, which improves rigidity and handling. Finally, one of the best modifications is to the driver.
That way, you can pinpoint exactly where your car needs work. Follow more updates from MotorBiscuit on our Facebook page.
