My car(firebird) has landrum leaf springs in the rear. I bought the car recently and the guy said that the srings have been under there a couple of seasons. I know that they need to be changed, but what I am wondering is what happens when the springs wear out? Do they get softer? or what?

What I have found is.. they do get softer.. but they also lose alot of forward bite... the top guys in my area change them about every 5 races... sounds stupid but I tried it once, and if I had the money I would change them as much as possible..Pig

When leafs wear out, they don't really loose their rate, they loose their arch and ability to hold the car at the ride hieght they could when new, but more importantly, they loose their ability to resist the 'wrap up' that occurs under acceleration. Fresh springs can hold their shape better and give good forward bite, where worn springs are likely to 'wrap up' or turn into a 'S' shape from the traction of the tires.
