And we couldt figure out a good spot to “dock” a phone up above their heads on that panel. Also we couldn’t find any units with rear usb or anything else that would work, locally, and in their price range. We had one night to get it all done, not enough time to do solid logistical work ahead of time.
Its tough to tell.
$2600 or so in hardware: front and rear bags/shocks, line, push connect fittings, valves, tank, compressor, gauges, relays, fuses, switches, etc.
20 hrs installing the front and rear kits and running lines to the trunk.
8-10 hrs plumbing valves, wiring relays for the valves, compressor, etc in the trunk.
2 hrs making a switch panel and wiring them
2 hrs making a gauge panel and plumbing/wiring them
8-10 hrs framing and doing the hardwood floor ($80 in materials), attaching he hardware bellow, etc.
So 42 hrs (rough est) for a show ready install start to finish.
If you got a prewired switch box. Put all the valves and what not in the spare tire well, tank bolted to the floor behind the rear seat, and more or less left the trunk stock the cost goes way down. There is a lot of time getting all the stuff under a bamboo hardwood trunk nice enough to be a dinning room floor! So knock off 12 hrs doing it without a bad ass false floor trunk.
All said and done, as you see it in the Audi: $5750
Also keep in mind the hardware is top shelf stuff. AirLift fully adjustable comp/rebound, threaded bag mounts, bolt in car specific, $300 compressor, good valves, etc. Prices come down a bit if you shop around and find other kits and/or components. Also the audi was dont with all options, so a bare bones air ride install is a lot cheaper too.
