I bought a set of sway bars for my car, The install kit came with two size tubes for the link height, a 4.5 inch and a 3.5 inch. What size would work best for my application. Since I lowered the car I noticed that the front tires run against the sway bar. I am thinking that the links are to high and pushing the bar up and out towards the tires.
Use the tubes that will position the ends of the sway bar level with the ground. When I lowered my 'Bird, I had to fabricate the end links because I couldn't find a link of the correct length.
