Yes I have installed one. I don't have mine buttoned up yet. I need some shocks, springs, hubs, etc... I did a bunch of measuring and figuring before I did anything. I also bought a chassis design book so I could educate myself on suspension geometry. The CPP kit, actually will give you more of a 3-4" drop with the "stock" style spindle by my calculations. I don't want a low rider, so I added some material to mine and trimmed down the spring hats.
