FWIW: Two weeks ago I emailed Agile, explaining I had tried to order The RIP kit before with no response. This time John emailed me back, then called back, promptly. We discussed the kit, and I put in an order. I received it within three days (CA to CO) and installed most of it this weekend. I put in four shocks and the two front coil springs, but ran out of time installing the DE-Arched helper spring in the back. First impressions are that this kit is awesome! This is my second Quigley, and there is no comparison to stock. I've been driving up and down my version of the White Rim Trail (AKA 29th street) for several days now, and I have yet to bottom out. With the stock setup, I had to drive around with my mouth open for fear that I would hit a bump and lose some teeth! I think total height gained in the front is ~1.5 inches, give or take.
