actually the best set up would be the FSSB. front, back and side to side. Meaning you have four valves, one for each tire. I have a set of air shocks on my truck (rear only, single valve)when carrying a load. My truck is also lowered. The shocks works fine when going straight, but when you make a turn all the air from one side goes to the other, hence the truck bottoms out, this is because I have only one valve for two tires.
Just a front to back system will work fine for driveways and such. But the FBSS will make your car handle the twisties like they were meant to. Ive also used them to level the car. I got a friend that is much heavier than I. all you gotta to is raise his side a little.
It the best of both worlds, Good riding. plus performance and the ability to adjust everything in between.
You will have to have some space for the compressor and a air tank. the compressors are pretty small. and the air tanks comes in various sizes starting from I think 1 gallon. You can also omit the air tank and just run the compressor, but the time it take to raise the car gets alot longer. If you run a air tank you can use a fitting and hose to fill a tire or such.
As far as space goes, you can always use the rear seat area. basically build a box around it and carpet it. As an example in my rear seat area I've got a 10" sub woofer, an amplifier, the ecu for my efi and a MSD box. plus around 6" clearance to the top of the speedster body.
All in all an air ride setup could cost well over $1500 plus the adjustable front beam. But if you got the skills like Cory it should be way less.
