Ken L from Fairfield, CA said, "I mounted the sway bar a few days ago - it was an easy installation. The sway bar improved the handling, but I believe the bar should be sold as set - front and rear - not just the front by itself. I am in the process of trying to locate a rear sway bar and new set of struts and shocks, so essentially the car will be set up to perform better than original with the new sway bars."
