Your Spyder has an independent front suspension. The sway bar is used to link both sides so they work together, but opposite each other. When you turn, the outside wheel rises up while the inside wheel goes down, with respect to the frame of the Spyder, causing the Spyder to dip (lean) toward the outside of the turn. The weaker the torsion of the sway bar, the more dip (lean) you have. Ron's bar has more torsion than a stock bar and gives you more control. He really has it figured out very well. Take a lot of fast, tight corners with your stock bar, then replace it with Ron's. You will notice a big difference in handling.
