My car sagged in the back because of the rubber spring isolators.. you might want to check those out before you get new springs and all that, so you don't have to take everything apart again to fix it later.. I have kyb front struts and quad shocks with koni reds on the back, and Motorsport lowering springs all around... I like them alot, the car is nice and firm and handles well! You should do the other bushings too while its apart!

Good luck!
