Is there any video that compare the Coil vs Air suspension ? For example, follow the exact same path at same speed with a glass or water or what ever could be used to display how bump are handled. I live in the Quebec, Canada were we do get lot of pot holes, and really bad repair works ! I'm wondering if the ride would feel more comfortable with air, or the weight of the car alone with coil give the exact same comfort. Seem everyone only talking about the controllable height. Also, anyone ever had issues with their air suspension so far ? That the other thing that worried me. I'm hoping to have a worry free for quite some time, and the day I do have a worries, I want my cost to be relatively low to fix it.
