F/B - Front/Back, front and rear independently adjustable.

Flagship models offer ungraded valves, model/number of compressors, and accessories. Custom packages available as well.
I have successfully installed one of these kits in my A32 w/ JIC FLT-A2 coilovers. I am prepared to answer any questions you guys may have.
Prices do not include PayPal fees, shipping, or sales tax (TX residents only, 8.25%).
the bag installation can be as simple as disassembly/reassembly using the provided parts. you will most likely have to trim the lower spring perch to prevent rubbing. i installed mine over coilovers so this wasn't an issue.
no modification to the chassis for clearance is necessary on a basic install.
other than that it consists of mounting the valves, tanks, and compressors, running air line and power wire, and wiring the valves/switches.
it could easily be a diy install, although a professional (or at least a buddy that is familiar with air suspension) install is always recommended.
fyi you guys, the prices listed are regular prices. i had previously listed group buy prices but gave up on getting multiple buyers together at one time. if we can get a few buyers together i can do a group buy discount (~10%).
