Cons: Since it is so low, beautiful women flock around at car shows wanting to sit right on the hood for photos, prone to damaging the hood
Well, I suppose all the above is left up for interpretation pro or con. From experience on my 5S cars, I would not have a air dam car without some type of elevation set up. I have just seen too many cars banged up at the chin, and it just looks like crap.
On my red 5S, I have aluminum suspension shocks, but have independent raisers that are separate from the shocks where I can raise the car from a button in the car when I need to. Then when you lower it, it sits back on the normal suspension again. Positive is that it allows a couple inches rise when needed and it allows it to sit back on the normal suspension when done...negative is that it is a little slow and takes about 15 seconds to raise the car (however, maybe some independent systems made now are quicker).
On my black 5S it has the actual "Air Ride" system which allows the front of the car to raise and lower very quickly all within one unit, not separate like the red 5S. Con is that my set up doesn't have an automatic ride height setting, so I basically guess at what height I want it to ride based on the pressure needle reading on the dash, general appearance of the right height and how it handles. Way too high and it gets a little squirrely, and way too low it gets too firm. However, I choose to ride pretty low, right where it handles real well. I was talking with the air ride dudes at car show booth, and they said they have systems that go right to exact ride height if you want.
