Air Suspension

A friend of mine in high school owned the sedan version of this car -- 62 Cadillac Sedan DeVille -- his dad helped him buy it from a VP at Snap On Tools and it was imaculate. Alas, about six months after he bought it he was driving through the park on a nice sunny day, dropped a cigarette, quickly dove after it so as to avoid burning the spotless carpet, and as he returned to the process of driving plowed into a parked car.
 
This is a great thread and I am down to either using air bags or Ground Control coilovers. I will say that for me it is not about going super low... I just want to have the control to get every fender gap exactly right. The issue with cars is that even from the factory, there are either cars where the stock gap is not 100% uniform due to design or they are just off due to acceptable tolerances. Bear in mind I am not talking inches of differences of course. Significantly, at standard ride heights, especially on these older cars, the differences were not noticable because of the gap to the fender and the inward-biased wheel offset. Things however become much more noticable (to me at least) when the wheels come out and the fender gap goes down to say an inch. In this scenario, a quarter inch difference is suddenly apparent. Clearly either system will address this ride height issue BUT the proponents for air-ride advocate a strong advantage: The softer and more refined ride. One friend pointed out that top of the line Mercedes use air-ride and can only imagine that this is in effort of achieving the most refined ride and uniform ride height. This is is a great debate and for me the jury is still out!
 
I remember seeing a video on youtube a couple of years ago, comparing the Air Lift Performance suspension vs coilovers.
This video is made by the company that sells that air suspension, and they didn't say which coilovers they used as comparison, other than "a very well known brand of high-end coil-overs" in the comments under the video.
So this is not to be taken too seriously, just an interesting video that shows that aftermarket air suspension kits aren't bad (performance-wise) anymore. But it sure is expensive!

 
Just get coilovers. GC, BCRacing, KW, IRL. You can get the exact height you want w/o the fuss of airbags and storing an air tank/pump.
