I recently purchased some L-Tuned sway bars. They are purple in color. They measure approx 1 1/16" and 11/16" rear. Before putting them on i noticed my STOCK front bar is also 1 1/16". I thought the stock bar was smaller? Did i get a painted stock bar!!?? The rear is however larger than the stock one and also has 3 holes for adjustablility. I have an 01 is300, automatic. Before bothering to install them, should I invest in something else? Is the diameter the same but torsion greater?
