Try an actual air bag in the spring instead of a walmart football.

I've never had a turbo car before... but are you leaving with a lot of boost off the line? Maybe dial it back a bit and let it gradually build up... hopefully someone with more insight will chime in. Looks like you have all the right parts, just need to figure out how to have em all jive together.

Sounds like you're leaving too hard for the suspension set up. Try softer springs in the rear. The airbag is only there to counteract the torque twist. It doesn't do a damned thing if the rear of the car is 3ft high in the back. Some pics or videos of the launch would help. Also, a more detailed description of how it leaves and how you drive through it.

What does the car 1/4 mi (or 1/8th) at and w/ mph?? What converter, is the posi working? With 10.5 slicks you should have plenty of tire, what compound are they? Are you running sway contol? What RPM are you launching at?

This makes sense to me.

Gbodynate, you didn't mention sway bars. If your suspension is too stiff the rear won't load properly. I run a Hellwig rear sway bar which I like for cornering but it is currently set too tight. Check out the video in my signature. During launch the rear wheels should be forced down.
