air bags for inside the coil springs. Who is running these and how EXACTLY do you have them set up ? Same psi left and right or what ? Have they helped traction or not ? Have searched and founded very little info. Thx.

I do not have these but I do have some info. They are made to help traction. They are never set at the same psi. They halp the car plant the right tire. This is due to it wanting to lift due to TQ. The bag makes the spring stiff and not let the tire bounce up therefore letting it grip more.

Oh one last thing. Some guys just run the one on the right and say it is all you need. the left side squats and that is all you need.
Hope this helps.

Pretty much what I have read but thanks. Sure would like some real world experience, anybody ?

How would it hurt to air up both sides the same as opposed to only the passenger side ? THX again.

Anyone ?

After some experimenting I found that I liked 5-7psi in the driver's side and 25-28psi in the passenger, depending on track conditions... This was with radials or drag radials and an otherwise stock suspension on a car with a manual tranny.

I understand the passenger side psi but what is the theory behind having any air in the driver's side or why couldn't you have both bags aired up the same ? Just trying to understand ? Thanks,

When I used them, that's about the pressures I was using also. They're a tuning aid so what pressure works best depends on the car. Normally you only need a bag in the passenger side.

Under a hard launch, the diff is rotating due to all the forces being put on it. The driver side tire is being driven into the ground and the passenger side tire is being forced off the ground. Open diffs normally spin the passenger tire because of this.

Using an air bag on the passenger side, you're putting more resistance on top of the diff. This means it takes more energy to try and lift the passenger wheel off the ground. If you can keep the passenger wheel planted on the ground then both rear wheels will have more equal traction.

Buy a kit and sell half of it to a friend who also has a third gen. You can both have one bag to put on the passenger side.

If using 2 bags, you need some pressure in the driver side to keep the bag partially inflated. This prevents it from getting damaged.

How come you no longer use tham and thx for the info?

I actually found that the pressure in the driver’s side tire does make a difference in tuning how the car leaves.

The partially inflated thing… I don’t know if I believe it (it does say it in the instructions). I didn’t like what the air bags did to handling with any pressure in them so I would partially unscrew the shrader valves on them when I left the track, letting them deflate/leak and I never had an issue. It’s not like these things are super expensive if you have a problem with them anyway.

If you really want to sell off the second air bag remember that they fit just about everything with the same diameter coil spring… so the same air bag will work on a mustang and probably a dozen other cars.

I have a ladder bar suspension now. It's hard to lift one wheel off the ground. I can also adjust preload on the chassis by adjusting the ladder bars.
