ECS MK5/MK6 Adjustable Sway Bar Upgrade Kit - Rear - 23mm


  • Ex Tax: £189.95

If you’re looking to improve the handling of your VW MK5/MK6 Golf, GTI, Jetta, Passat/CC, or similar model, this is the best place to start! These cars have more body roll than desired and the stock sway bar doesn't quite do enough for most owners to be satisfied. 

Larger diameter sway bars have a higher torsional spring rate which helps resist excessive body roll. By eliminating the excessive body roll and changing the stiffness of the sway bars front to rear, we can improve handling characteristics by reducing understeer and keep the tire in full contact with the ground. By upgrading to the ECS Tuning Adjustable Sway Bar, you will experience less body roll, and a massive improvement to the handling characteristics of your vehicle, with virtually no sacrifice in ride quality. 

ECS Tuning sway bars are adjustable and allow for a “softer” setting, or a “stiffer” setting, depending on your driving preferences.
