Launch Video need help

I've slowed the video down so you can see it in slow motion. This is a 1.70 60ft
It looks like when I let the clutch go, the tire flatens and then bounces back up harsh, causing the car to spin, then it hooks and goes.
Is the suspension set to hit the tires to hard? Causing it to unload....
Or are the stock rear shocks just not able to control the launch?
Lower control arms are in 1 hole up from the bottom - MWC 9" with 4 holes.
Torque arm is 1 hole up from the bottom.
Pinion Angle is 2.0*

I've been watching my vids in slow motion the last couple weeks, and it's doing the exact same thing. My car has Comp Engineering 3-way adjustables on the back, so I put them on 70/30 (hard compression, loose extension, ) and it seemed to help with the "snapping". It still does it but it's not as violent and doesn't seem to unload the tires as quickly. You could try moving the front of the t/a up one hole so that it doesn't hit quite as hard.
What's the angle of your LCA's? If your car isn't lowered, you might try the stock LCA setting.

When you have a 6 spd in a heavy F-body you need a stiff sidewall slick to get the full benefit of dropping the clutch and improving you 60 foot which will then improve your entire run.
Call M/T up and they will tell you that you need to run a stiff sidewall on your car and it will help! Also when you switch to a true slick and take off the ET Streets you will be happy because you will no longer be in the 12 second club! Try M/T 26X10X15 ET Drags!
Good luck and be safe!

It is hooking the bog will go away with taking some hit out of the suspension. Upping tire pressure and controling the axle. Adding more power is not going to fix the issue you have in the video. The wheel almost hits the track. You can't get a car to leave when it is doing that.
