THE THICKNESS IS 22MM, IS IT STRONG ENOUGH?
--- A larger sway bar is not necessarily stiffer. Aftermarket sway bars are typically sold as either solid or hollow tubes. Since the elasticity of a sway bar is a result of cross sectional area, the overall diameter doesn't matter so much. For the most part, solid tube sway bars are stiffer than "larger" sway bars made of hollow tube. This is because the hollow metal tubing actually has less cross sectional area and therefore has less resistance to bending moments.
--- Stiffer sway bars are not always better. While increasing the stiffness of the rear sway bar in a front wheel drive car might reduce understeer, an overly stiff rear sway bar can actually induce oversteer and make the car difficult to drive. Likewise, a rear wheel drive car with an overly stiff front sway bar may tend to understeer. When it comes to suspension, the name of the game is balance.

HOW A SWAY BAR WILL AFFECT VEHICLE DYNAMICS?
--- Front Wheel Drive (FWD) Cars: A stiffer rear sway bar on a front wheel drive car will reduce understeer. Typically, a front wheel drive car will handle better with a rear sway bar that is stiffer than the OEM piece.
--- Rear Wheel Drive (RWD) Cars: A stiffer front sway bar on a rear wheel drive car will reduce oversteer. Typically, a rear wheel drive car will handle better with a front sway bar that is stiffer than the OEM piece. Some rear wheel drive cars, however, also understeer. If your vehicle understeers, front or rear wheel drive, a stiffer rear sway bar will make the car handle more neutrally.
--- All Wheel Drive (AWD) Cars: To put it simply, if you drive an all wheel drive car that understeers, install a stiffer rear sway bar. If you drive an all wheel drive car that oversteers, install a stiffer front sway bar. All wheel drive vehicles all handle a little bit differently, this means that choosing the right combination of sway bars will depend on how your specific vehicle behaves.
HOW AND WHY SWAY BARS WORK:
Sway bars are actually very simple suspension components. Sway bars are intended to reduce body roll while a car is turning. When your car turns, the outside of the vehicle will squat while the inside will lift and "unload" due to centripetal forces. This reaction is what is referred to as body roll. We want to reduce the amount of body roll in a performance vehicle because you are taking the weight from the inside tire and applying it to the outside. By doing this, the car is using only one tire to turn instead of two. This reduces the grip of your car and negatively impacts steering. A sway bar reduces body roll by acting as a torsion bar that transfers load (force) from one side of the car to the other. Sway bars connect the left and right suspension components on a car so that when weight is transferred laterally, both the left and right suspension pieces will compress. This distributes the turning forces more evenly across both sides of the vehicle and helps it stay flat through the turn.
