This mod was done on my 92 Accord so it should work for 90-97 Accords. I'm sure it will work for Civic and the other smaller cars as well but I think the shocks will be too long and you won't be able to go any lower than you can with standard shocks. The advantage is that you can have ride height adjustability at the touch of a button! That is of course assuming that you have an on board 12v air compressor, reserve tank, and switch/gauges.
Anyway start off by purchasing a set of airshocks for 1972 Lincoln Continental. Then cut off the eyelit mount on the airshocks. Next take your stock shocks and cut off the U shaped shock mounts (where they bolt to the lower A-arm).
Be careful not to cut too close to air shock cylinder so you don't blow the seals.
Now put the stock mounting U shaped bracket on the airshocks and weld it into place. (MIG welding is prefered because TIG applies too much heat near a sensive area on the shocks). Now all that's left is to install these in place of your shock/spring. The bottom will bolt right in since it is the factory mount and the top should slip right through the stock shock cup. The car rides on nothing but these shocks and air. They completely eliminate the springs from your car. Now I have a disclaimer on this mod. If you do this it will be for show purposes only. The reason is the car will ride like shit compaired to a shock/spring combination. Also it won't handle very well. Then thirdly it's not very reliable. Air shocks only handle up to 90 psi safely. This mod will only work for the rear of the car. The front is WAY to heavy for this to work. Even running them in the back I need to run about 125 psi in them to get the tires to run about even with the fenders. Anything less and they would tuck into the fenders and on 16's with 40 series tires that was LOW and rode like crap. 160 psi the car would ride fairly decent but I was always worried that the shocks were going to blow and leave me standed. Granted you COULD drive the car with no air in them but it would tuck rim and left the rear of the car only about .5" off the ground, with my wheels/tires at least. At times I would run up to 200 psi in the shocks and they held it fine but I wouldn't recommend it for any length of time. It went really high though. The gap between the tires and fenders then was about 6". Another thing is don't run the air lines to them together. Make them two separate air lines partially for redandancy, by mostly for handling. It already handled poorly, but it was REAL bad if they shared the same air. For example if you made a left turn all the air would shift from the right shock and go into the left one and there would be MASSIVE body roll and it would be difficult to recover from it.
Well if I still haven't talked you out of it yet, have fun and good luck!
