Pics from a WestCoastFords meet.
I usually keep the ride height
at around a 1.5" - 2.0" drop to keep the tire and
ball joint wear to a minimum. Pic courtesy of WestCoastFords.
This is my 1990 Thunderbird SC. I am the second owner of this car and it has every option available from black leather interior to the fold down rear seats. The only thing it does not have is a moon roof. It is still a project in progress. All the work on this car has been designed and done by me. The next buy will be 18" chrome wheels. I am not sure which to go with yet. You can see some other pics as well as pics of other t-birds on baggedbirds.com.

AIR SUSPENSIONI custom built the front brackets using a similar design used for the ride tech. shockwaves desinged by Scott McKeeman, owner of baggedbirds. A... Show morell the steel is 1/4" thick. _________________________________________These are a few diagrams I made to show how to wire up the relays needed for a compressor override switch, how to setup the valves, and which components are needed. Feel free to contact me with any questions. This is a diagram of how i wired up a switch to override the pressure switch, which allows to turn off/on the compressors. 40 amp relays are used. The fuse rating in this picture is just for the sake of an example. You will need to use the appropriate rating for your application. I have gotten questions on how to run the valves, so this is a simple diagram of one way to run the lines. These are the components you will need in order to install an air suspension. 1.) Pressure switch. Most viair compressors have a 150 psi max rating on them. 2.) Tank. 3.) Water trap. Used to filter the air that enters the tank from the compressor. 4.) Gauges/Switches. 5.)Compressor. Continuous duty cyle is a must if you are switch happy. 6.) Valves. 4 for shared front/back, 8 for independent bags. 7.) Air line. 8.) Air Bags. 2500lb firestone bags are the best fit for the rear suspension. Your choice of a front suspension is either mark 8 air struts, a bag/shock combo, or air cylinders are used in the front.Various fittings as well as wiring/connectors/fuses, etc. will need to be purchased to fit your application's needs._________________________________________ These are the airwaves that i used for the front suspension. They are 2500lb bags and are about the same diameter as the shockwave. The front brackets were measured and cut to allow the front suspension to either lay or be .5 to .75" from laying the cats. On 3.8 n/a and SC t-birds, the cats will touch down first as well as the oil pan nut so you have to be careful when the car is slammed. The upper bracket is a circle plate with a diameter of 6.75" and mounts to the shock tower using new bolts and nuts. This is the bag bolted to the lower bracket and ready to be fitted into the suspension. The bag here is test fitted to see if it wil clear the spindle and the rear of the wheel well. New holes for the lower arm bolt can be drilled for different wheel/tire combos to determine how low the car gets when fully dumped. Here is how to looks as it clears the spindle. This is how close one of the cats gets to the ground. The rear suspension is a simple bag and cup assembly. The bag has a single 3/8" port. The bumpstop must be trimmed in order to fit the bag assembly in between the spring pocket. A hole in the lower arm was drilled in order to allow the bolt that holds the lower cup to pass through. The steel bar that is welded to the lower cup is used to prevent the cup from turning or shifting, which is normal when the bag is inflated from a full drop. I heard that the '94 - '95 birds do not have this hole in the the spring pocket. With those models, the upper cup is usually tacked to the body, although this makes it more difficult to access the fitting or pull out the bag. But I did lower a friend's '97 lx so i know that the '97s have it also. The finished bag assembly. ______________________________________________________________________________ Just for fun, I experimented with MARK VIII BAGS Lincoln Mark 8 bags are another bag option that the t-bird can use. This is how they compare to an eibach sping/shock assembly. I experimented with them just to see for myself the drop and lift on a stock wheel/tire combo. The solenoid housing was cut off and a 1/4" hole was tapped and a fitting was used. It was welded for strength and coated in jb weld to be airtight. As you can see, it didnt match the rear drop.This is how low it got. It can get a little lower if low profile tires are used though. Show Less
