I personally got myself a 3" Rough Country lift (spacers on front wheels, and spring + shock obsorber on the rear wheels). The rear tires suspension is too stiff.
This is my 1st lift kit, and my conclusion is that it sucks when the car is not loaded, which is the condition most of the time (so it sucks most of the time)
I will certainly put more money for my next lift kit when time is due. I personally like having the ride of a Cadillac
