Default S8 Air suspension build

Hello all,

I've been working on an air build since June. By working on the build, I mean I've been waiting on a company called BagYard from Austria to build a bolt-on kit for me. They continue to drag their feet, so I'm done waiting. Here's what I'm doing then.

I already have my management, compressors, tank, etc. I'm using twin Viar 444c compressors, a 5 gallon aluminium tank, and a management system called Accuair E-Level. E-Level uses height sensors to determine height instead on bag pressure. This negates the need to have additional gauges in the interior, only a touchpad controller is found. Another benefit is that when weight is added to the car the suspension automatically compensates and levels the car to the desired height. The system has three preset heights and also allows for full up or full down at the press of a button, or one could change heights on each corner as desired. The system uses a four corner, eight valve manifold. Lines are 3/8 inch, but with this manifold height adjustment won't be jerky or unwieldy. Here is info on the management:

And the manufacturer:

Now, I had planned on using a bolt-on kit, but BagYard has ridiculous wait times, though their product is top notch. They are also the only bolt-on setup available. An American company called Air Lift has released a universal system though that allows for welding to the body of the strut in order to mount correctly. Here is info on that strut:

I'll be using a bellow bag setup, and probably a dampening adjustable strut to set ride comfort. For the rears I'll be using a double-bellow bag by Slam Specialties called the SS-5. I'll have to build a set of "cups" or bag mounts for the rear. I'll use either a bilstein shock or the stock S8 unit.

I'm building a false floor and mounts for management, etc. in the spare tire well. I'll be having one of the armrests modified to hold the touchpad eventually, will sit flush with the top of the armrest.

The one thing I need to know is the stock S8 front strut dimensions, IE compressed height and extendended length. If anyone has some struts out of the car that would be SOOO helpful.

I'll post more info and photos in the AM. I hope to have the build complete in the next 1.5-2 weeks.
