I stumbled upon an Ebay member that was selling a complete set of Air Ride Technologies components, and couldn't help myself from buying it. I ended up with Shockwaves up front and back, and the RidePro 4-way control system. I think I will have a great time with this setup and be able to get the ride adjustability that I want. I took a few pictures of the system in the fully extended position and fully collapsed position. Lets put it this way - I had to raise the car up a bit just to get it over my air hose laying across my garage - the lower portion of the front fenders were going to hit it... Now that is LOW!
