I run 5lbs in the drivers side and 17lbs in the passenger side. Start at ~12-15 on the passenger side and keep adding air until it launches straight. I use airlift bags and although I don't recall max pressure, I seem to recall it being rated very low. Ignore the rating. I've had as much as 30lbs in mine before and it didn't pop smile.gif BTW, there is a limitation to how much these air bags will help. If you find that no amount of tuning the bags helps the car leave straight you may need to preload the passenger side with an adjustable control arm (shorten the arm). A rear sway bar/anti-roll bar will help the launch quite a bit as well.

I run 0 in the left and 12-14 (doesn't seem to matter) in the right. Max is 35 psi, min is 5 psi for driving. For the racing you can drop to 0 since it is for a very short time. If the car goes right add air to the right bag, if to the left let some out.

I've been able to get mine launching straight with the air bags(near 0 driver side, 30 pass, side) but still have a problem with planting the right side tire, and wheel hop! graemlins/angry.gif

My car needs an alignment bc without the bags when accelerating it'd pull towards the passenger side.
Thanks for the help i have a race to handle tommorrow night :D

Isn't running 0 pressure a no-no? I run 5 on the left, and 12 on the right with lowered suspension, but I don't race so I guess that's not much help.

The 5psi min is to keep the bag from getting a hole rubbed it or a fold crack forming. For the short time the car is moving at a race (strip, lanes, and return road) this isn't much of a problem. On the street 5 psi should be maintained
