Hello all. This is my first post on site. I am going to put my 66 4 door on air. I'm new to air ride and was thinking of purchasing a kit that comes with the VU4 manifold. 1 tank and dual viar 480s. I want the car to lift quickly, is the VU4 going to be a slow bag fill or pretty fast? I was planning on 3)8 lines. I'm also open to any other suggestions for a setup also. Thank you.
