I'm undecided between getting air bags or get the Boston suspension kit for a 96 Deville so I ask anyone this question:

Is it smooth on bags as it is on passive struts? Pros and cons from anyone. I like the fact that I would be able to get it high enough (I like the 3" difference and then drop it while parked with air bags. on struts I can achieve the 3" lift and possibly put 20" shoes. I just want to make sure I wont look back and go with the other if it feels the same. Thanks in advance.

Cant you get 20"s on with out the lift?

I had seen a 97 deville with them with the stock height (i believe) and it cleared turns but not too sure if he had to do anything with the wheel walls.

he mighta cleared a turn but i bet his radius wasnt like it used to be.. you should ask somebody who sells custom rims. they'll tell you whatever you wanna know, if they think your going to buy from them.. or you're cool.
