you have made up your mind about a sway bar topless, so i guess it no need to tell you this, but if you have weak springs under your car then a sway bar is not the answer. you need to pull a spring, have it tested and if its to weak for your wt. then you'd better off spending the money on HD springs. if the springs is right then you don't need a sway bar for normal driving. sway are made to work a hi speeds. you can fix it with a sway bar, but far as i'm concerned it not the right way.
