I am about to changes the springs and struts in my 99 se v6 MTX. The car has 70k miles on it. How important is it to change the strut mounts? I will be going with the roush springs and most likely KYB Struts. The strut mounts cost almost as much as the struts (well for the fronts anyways) Also, what about the strut boot? I'm not even sure what that does. I don't want to spend unnecessary money but at the same time I don't want to half ass it.
