E3's use struts in the rear. The photo of the system on the floor shows a rear OEM strut next to the Air Lift strut. It almost bolted on without any mods.Awesome job!
However, I'd somehow beef up those rear shock towers since they are now carrying the full rear weight of your car.
I'll need to drive it a lot more to figure out the ride. Once I find the ride I like I'll spin the struts up or down to the height I want.how does it ride? Super stiff?
With airbags, unfortunately the higher you go, the stiffer you get. You may need to lower it some more to get a better ride???
