Tunning my eibach drag launch springs

[notchback501993]

My left wheel is hopping. How much air pressure do I need in my air bag?

I assume the quad shocks are gone since you have the SSM lowers, if not remove them. Start at 13psi and go up or down in 1lb increments and see if that helps.

By LEFT wheel you mean the Drivers Side correct?

What about upper control arms? I don't see them in your sig unless your running uppers and lowers from SSM.

I thought the air bag was only to prevent squat, I didn't know they controlled wheel hop, unless they are firming up the spring.

I still have stock upper control arms. When I launch, the driver's side wheel is hopping. It is evident by the staccato marks on the street. I installed the drag launch kit years ago and just set it cause the car did not need to squat control. I think that the left wheel is unloading and the car is squatting towards the passenger side too much. I will start with the 13psi. Thanks.
