Project S550 Mustang GT: Installing Airlift Suspension Digital V2

,

The rear kit fully installed.

The last piece of the puzzle is hooking the wiring up to the battery and then running calibration on the system. The airlift kit will calibrate itself to learn the tank pressure, ride height, and corner air pressures. Once this is compete, you can begin to set your air pressure presets.

Before the installation, we measured the ride height with the Eibach Pro Kit springs. We felt that this was a perfect ride height for daily driving. We carefully adjusted the air pressure until the right measurements were dialed in. Preset one was utilized to set this as ride height. With this setup, it is at 52PSI in the front and 70PSI in the rear. Preset one is also set as the auto rise setting for the car. With this setting enabled, if you air the car down or it has a leak, once the car starts it will auto rise to this setting.

We preprogramed two additional settings into the car. Preset two is the monster truck setting with both the front and the rear at 100PSI. This raises the car to higher than stock and helps to the car get over obstacles without scraping. It was also very helpful when we visited the alignment shop after the install. The next preset is the photo/show height. This is set at 20PSI front and 40PSI in the rear. There is also the option to fully “air out” the car at 0PSI, but we aren't not quite into that style. Although, it is hilarious to hear peoples’ comments about how you drive and turn with it that low.

 

The car completely bolted back together and sitting at ride height.
 
Here is the car at 0PSI for those that like it extremely low.
 
This is the car at photoshoot/show height- 20PSI/40PSI.

We spent the first few weeks after the install experimenting with the dampening adjustments. We found 24 clicks to full stiff in the front and 28 clicks in the rear were optimal for our taste and local road conditions. This setup provides a firm ride that is not overly harsh and handles very well. Honestly, this system has performed better than we had ever expected. There are zero issues with the system leaking thus far or any other reliability issues, and the handling is fantastic. In fact, we recently took a hardcore coilover guy out for a test drive. He was amazed at how well the car rode and handled. Apparently, he was so impressed that we just found out he ordered a kit for himself.

            The one area of the kit that we were not 100% happy with was the tank and compressor location. The tank blocked being able to use the trunk to its fullest capability and the compressor was very loud being mounted on the rear wheel well, even with using the Dynamat. As a result, we went back to Hypermotive and ordered a smaller tank. This allowed us to move the entire system into the spare tire well, cutting the noise drastically and giving all the trunk space back. In our opinion, this is the way the kit should have come from Airlift and is the way we would recommend everyone installs this portion of the kit.

 

Here is the final location of the air system. Everything is now hidden under the cargo mat and is completely out of site. 

We know there are going to skeptics out there- it is heard from people all over forums and Facebook about how bags are for groceries and semi trucks. But, take a second to look at the success Cody Miles is having in his 2007 Subaru STi and then look at an air suspension with an open mind. Today's air suspension systems have greatly improved in performance, and we also even have one on our infamous project, Project V8 RX-7, that we will soon be testing on track!
