Improvement with air bags

What kind of 60'/e.t. improvements are you guys seeing with Air Lift air bags. I have 3.23 non posi and have run a best 60' of 2.37 and a best e.t. of 15.09@93 with 2.50 60'. I am thinking of installing a set. Just curious how well they have worked for you guys.

i'd get a posi first, but they should help out a good bit and allow you to fine tune to preload in each bag. i'd run a seperate line and gauge to each bag instead of single line to both.

Come on guys. I have see you guys write about air-bags, so I am assuming that you use them. What kind of results have you seen?

They're a tuning aid. If properly set up, you could get an open diff to hook up like a posi.

I have no idea if they help my 60' times at all. The drivers side bag leaks down so there's rarely any air in it and I run around 25 psi in the passenger side. For me with ladder bars and a spool I doubt I'd see any difference if I pulled the bags out. The car launches straight so I leave it the way it is.
