Default Too much rear squat?

I have BMR rear springs, V6 springs in the front. I can get it to hook, but it doesn't leave as fast as I think it should. 1.73-1.80 60' times are pretty normal for me on 17" MT radials.
Here are a coupld of pics from yesterday. (from my videos)





Input?

It's hard to see in your pics, but yeah, looks like it's squatting. Squat is bad.. mkay?

Here's a pic of my '94. I'm not the "launch king", not even close, but I keep the rear shocks stiff enough to plant the rear axle to the track. Note how that even though the front wheels are up, the back is not squatting.

Car was on a 28x9x15 in that 2001 pic, and I had V6 springs in back. It squatted like four inches in the back.

the UMI adjustable tunnel mount T/A that we put on a friends trans am really helped out the squat with it adjusted to -2.5

if you slow it down, you can see the car lifts, planting the rear...

I have BMR springs all around with Hals. I cut 1.60/1.61 on a 17 in BFG. I had the shocks set at 5 in the rear and 1 in front, no front sway.

You don't want the rear to squat you want it to push off the ground, hence the stiffer shock settings.
