you are reading me wrong. The eLevel CHECKS to make sure the height is at its predetermined level every 45 seconds. It takes milliseconds for it to adjust. Maybe a second at the most.
Good points, all very valid. Yes there are more issues that could arise, but a properly installed system will be just as reliable is my point. Nevertheless you are right - more areas of concern than a tradtional coil. If that bag you saw that got rubbed through was tested properly they would have caught that. When I set mine up, I jacked each corner to make sure there was clearance for the lines and the bags. You would notice that immediately if it was rubbing, or even coming close to the frame. Again this is kind of null since these "kits" are specifically made for the application and that is something thats checked by the manufacture before its sold.
Do you have your foot to the gas as soon as the car is turned on?

Also, my managagement system along with the elevel have "rise on start" which will go automatically to your ride height as soon as its powered on. So that 6 seconds just turned into 2-3 lol.
Also, I wasn't saying you were attacking bags, and its the reason why I also said i'm not attacking your comment because I know it could easily be seen that way. Just engaging in conversation
Shame on your friend for not showing you the ropes
The ONE thing I don't like so far about these pressure based systems is that going from aired out to ride height is not always 100% accurate, where as the height based system (elevel) always was, and if it wasn't it would get adjusted out anyway automatically. Thats my only gripe. I went from aired out to ride height, started backing up and heard my exhaust scraping when I hit a few bumps in my friends driveway and was like wtf? So now I go from aired out, up to a higher setting than my ride height, down to my ride height. Yes its kind of stupid lol.
