I have a 78 fj40 that rides terrible that I am going to replace the springs on . I've been told to improve the ride (ie softer) I'll need to do at least a 2.5inch lift. I am considering safari 2.5 inch front and rear. Any thoughts? It's a daily driver with a little gravel and woods roads travel on the weekends. I'm looking for the softest ride for the last lift.
