Took me a Saturday to install but is well worth the time and cash. The drop was noticable but not extreme, about a inch in the front and slighty more at the rear. The ride is just a little bit firmer than stock normal driving, but when pushed, it goes right where you point it. Best of all that most annoying front end clunk is gone. So far! I have one question of anyone else that has installed this kit. Did you get any instuctions, I did not, I'm wondering if Roush has alignment spec's of their own. or if I will need to install camber bolts. I would like to install these myself before taking it in for an alignment, if I need them.
