Sorry but why would you want to air spring the car.. they seem to be the misguided design of a marketing department! Lots of folk get up to this (well on non G vehicles) but few seem to understand the large compromises created.

The spring rate of an air spring is pretty close to zero lbs/in .. so when you put load on it .. it compresses .. due to this it turns all on road handling to a very poor thing.. it just rolls until you hit bump stops at which point spring rate goes to close to infinity (well alright G's have an anti-roll bar but that cannot stop all of this). My other half's '02 Disco 2 :oops: has an air sprung rear and if you put it on a bumpy wee road .. you have to slow right down (ie half the speed any steel sprung vehicle would) as the back end becomes so disconnected from the chassis to the point that you cannot feel/predict where the back of the car is .. and hence where the front end maybe pointed, not to mention the crashing from bump stops causing juddering .. a steel sprung car would not do this. It is fine as a motorway cruiser and does a fair fist of normal trunk roads but small twisty bumpy roads complete shatter it.

For ultimate off road very soft springs allow you to reach down for traction al-la Rover bits.. but Diff locks compensate a bit for our stiff suspension .. so air springs are good for totally non road vehicle .. in which case just get a Quad bike, Muskeeg or Unimog... soft suspension as standard, on road gets more interesting :lol:

Ah well .. I guess it depends on your goals but just be aware of the compromises.

Sorry .. Techno speak from someone who works with spring rates and suspension in machinery for work .. and plays with sports cars that need to handle .. only needs 4x4 that does what it says on the tin (compromised road car with best traction solution) but uses real off roaders for cross country work:shock:

... now dons fire proof clothes while retreating to fire proof room... :twisted:
