I did forget to add, adjustable sway bars are kinda pointless. If you need to tighten it up a bit, so for example you have a 15mm bar, you can get bushings for a !4mm and force em on to hold teh bar tighter. To looosen em, you can simply find some 1mm washers and put them on the bushing mounts that are U shapoed. This gives the bushings that 1 mm gap to expand a bit. Ghetto and maybe not the best, but worked for me. Do realize loosening or tightening the sway bar in my methods will cause the bushings to wear out a bit faster, as one way os over dsoing it a bit, while the other allows the bushing to basically be pushed out of shape evrytime the suspension goes up and down.
real adjustable sway bars have endlinks in which the length can be adjusted. This allows adjustment to how firm a grip the sway bar has on teh control arm. If you lengthen the endlinks, you are increasing how "down" the sway bar is pushing, while shortening it will have the opposite effect. Shortening it or lengthing it too much puts a constant tension on the bar and can cause iot to warp from the constand abuse of being bent.
