thank everyone. the wheels i already have, just need to save up for the tires and massage the fenders a bit. you can see the wheels stacked in the background when i was doing the carpet installation (tease).

here is a pic when i took her on her maiden voyage this morning. i found that running 90psi up front and 45psi out back works well. it's pretty stiff so i'll adjust the dampening. there is also some knocking coming from the rear. i suspect the top hats. so far the pressures are holding constant!

That is a nice and clean set up and I like all the pics which gives the next guy a better understanding of how to get it done.

$800 (new) - BC Racing BR-type coilovers
$800 (new) - Universal Air Suspension Aero Sport bags w/brackets
$30 (new) - 1/4" airline
$100 (used) - SMC 3/8" valves
$200 (used) - dual Firestone compressors
$40 (used) - 5gal chrome tank
$20 (used) - Norgren water traps
$20 (new) - Viair 165/200psi tank pressure switch
$70 (new) - Air Ride Technologies digital gauge (made by Dakota Digital)
$100 (new) - Dakota Digital pressure senders
$60 (used) - EAI switchbox

plus about another $200 for fittings (some at $8 each!), wood, wiring, connectors, heat shrink, loom, carpet, adhesive, etc.

rough cost $2440 or so !

How much 1/4" air lines did you use? one of the few things I have left to order and was just wondering how many feet you'd recommend

Nice bro! Identical to my UAS setup! I have the Dakota air gauge and everything else too. Just minor differences like the switch box. I have Bilstein shocks. How do the BCs ride?

i had 50' of airline, and used about 40-45' of it. i always cut longer than necessary just in case. also use a proper cutter, not wire cutters or a knife! they have cutters specific to tube cutting. if the airline is not cut square it will leak.

i'm sure you have the better dakota gauge with the tank pressure too. i have to press that mini button to read between front to rear, not convenient but heck it was $70 new! BCs ride amazing but i'm comparing to stock. i have set the dampening down to 20 front, 15 rear. do your bilsteins have adjustable dampening?

The Bilsteins for the 2LS do not have any adjustability in damping. (Dampening is what happens when you let loose the hose on something )
