Any idea how long springs last? I'm about to hit 100k miles and was planning on replacing my shocks/struts...should I replace the springs while I'm at it? I want to stick with stock SE springs even if I replace them.
Thx

 

my friend's 95 max with 250k riding on stock suspension...everything is like new

 

I don't think there is any rule with them. They could break (especially if you owned a focus ), but that's pretty unlikely. Why not lower?

 

my rear is messed up, being replaced soon. 120k

 

Terran is right, there is no specific guidelines for them. They can last you 500k miles, or 100k miles. Most people will tell you that springs outlast your car, I'm on that boat.
