with that much of a drop, especially with over 60k on the stock struts, I would certainly think about changing them out, unless you just want the look and don't mind bouncing down the street and people laughing. Everybody makes a big deal about buying upgraded struts, its a little investment, and it is well worth it. You get upgraded performance, better ride, and you don't bounce! I laugh everytime I see someone lowered and they are bouncing all over the road.......you can tell when somebody is sporting stock shocks when the car is moving, at least I can.
