how do you tell if you need to change the spring preload? do you ever change the preload or just use a stiffer spring. also on a j-bar with rubber bushing do you ever change the preload on it? what dictates that you change either one of these? thanks in advance. just starting out and dont have a clue what we are doing.

posted April 17, 2002 11:00 PM The spring rate will dictate how soft you want to be on the contact patch of the tire. When the track is tacky, you will want more spring rate to get the car to dig in faster, and a softer setup on the slick track which will help traction. If you preload a spring, your adding spring rate. You are only going to get a certain amount of pressure on that spring, if you change to a lighter spring, your just telling your suspension that you want it to rotate farther until it gets to that same rate. It only dictates the movement in the rotation. I hope this helps.
