Coilovers - Pros - less expensive...easier installation [no compressor system to install]. Cons - no ride height adjustment...no weight change compensation...no spring rate tuning without changing conponents.

ShockWaves - Pros - ride height/spring rate adjustments can be made for handling tuning and/or aesthetics with the push of a button. Cons - The ShockWave units themselves are slightly more expensive, and the compressor system will add $1500-$2500 to the overall system - The ccompressor system installation will take an additional few hours to install.

Leaks? Only if you do a poor job of installation. We use DOT approved airline and bubble tight solenoids. Handling? An airspring can be a significant tuning tool...almost to the point of being an unfair advantage. As with any tool you must educate yourself just a little about how to use this tool effectively. Most give up and use coilovers.
Ride quality? We can make a coilover ride almost as well as a ShockWave...until you change the load in the car...people, luggage, fuel, etc.

If you want simple and inexpensive...coilover. If you want no compromises...Shockwave. Also, know that our coilovers and our ShockWaves share the exact same shock cartridge...the coilospring and the airpsring unit are interchangeable.

My last couple of road course/autox cars [48 Hour Camaro and the 33 Ford] have been coilover...just because thats what we were trying to promote. This year...my Mustang is on triple adjustable ShockWaves. It is reasonably fast.
