i sell air cylinder kits in phoenix, AZ. i know they will work on pretty much any car with a strut-based suspension. there are kits out there for hondas, acuras, mitsu, etc, but no g20's yet. basically, i offer a kit consisting of four air cylinders, electric valves, a 10 switch box, all lines and fittings, one compressor, and a 3 gallon air tank, and you can opt to add gauges, upgrade to multiple or larger compressors, or bigger tanks if you like. prices start at $2200. this setup would include everything you would need except for the mounts, which i may offer in the future. for now, there are some steel fab shops thta will make the mounts on a CNC plasma, and assuming all the measurments are right, have the potential to turn out very nice. if anyone is interested in an air cylinder kit, email me at
[email protected] and we'll talk.
