Frequently Asked Questions (FAQs)
1. Do performance sway bars make a difference?

Upgrading sway bars is an affordable and easy modification to enhance a car's balance and dynamics, making it a recommended upgrade for those looking to tune their vehicles.
2. What does a performance sway bar do?
A performance sway bar serves multiple purposes. Firstly, it helps control and reduce excessive body roll during turns, ensuring better handling and safety. Additionally, it helps maintain proper wheel alignment and improves overall grip on the road, enhancing the car's stability and performance.
3. Do sway bars improve steering?
Yes, sway bars can improve steering in a car. By reducing swaying and body roll during cornering, sway bars enhance car handling and stability. This, in turn, helps keep the wheels firmly planted on the ground, resulting in improved steering response and control.
4. What are the benefits of upgrading sway bars?
Upgrading to thicker diameter sway bars offers several benefits. It helps control excessive body movement and improves overall body control, making the vehicle more stable and predictable. This upgrade can often restore or significantly enhance the car's stock handling capabilities, providing a better driving experience.
5. Do sway bars affect body roll?
Yes, sway bars have a significant impact on reducing body roll and improving handling. They connect the suspension on one side of the car to the other and limit roll during cornering. This helps counteract the body roll force created by centrifugal forces when the vehicle enters a corner.
6. Do stiffer sway bars affect ride quality?
Mildly stiffer springs and sway bars can actually improve ride quality compared to stock components. Stiffer sway bars keep the car off the bump stops more effectively, resulting in better ride comfort. Therefore, upgrading to stiffer sway bars can enhance both performance and ride quality.
