I've done a bit of research myself as well. Tim is correct if you change the pressure you change the ride height. That is not company specific, that is a function of physics. The only way to adjust stiffnes or ride quality and hold the same ride height is with adjustable shocks. If you want to maintain the same ride height all the time Jody, I would suggest investing in in car adjustable shocks/coil overs. I have seen them somewhere. I believe they use oil that responds to an electric field to change it's viscosity. Therefore it changes the dampning rate with the same valving. I think there is also a product that changes the valving electronically. The least expensive option would probably be to do what we did when we were racing. Have a set of coil overs you run on the street. Then have another set with the shock valving, springs, etc. you want for the track. Put them on the car, adjust your ride height and pull them off. When you go to the track swap them and you are in bussiness. It really ends up being easier than it sounds. We did it when we went from one track to another. The double adjustable AFCO's are nice, you could have them setup with your track springs and be able to tune pretty precisely. JM2Cents.
Good Look, let us know how it goes.
