I felt like it handled pretty damn nice but I never competed with it or anything to put them to their limits. They were nice running through the hills at a pretty considerable pace however. They were livable on the street and not much worse than factory in terms of ride quality. They're progressive so they're meant to be nicer riding as opposed to linear springs.
How did you do your alignment? I planned on installing that kit and then just taking it to ford and having them deal with the alignment. That's what Ford Racing told me to do
