Wow! Awesome video Ron!
Looks like a wee bit of rear squat but not too bad. I am still on the factory air suspension, so no 'drag bags' but I do have the adjustable Koni's in the rear adjusted to full max.
Hard to say, but the second video 'sounds like' there may have been a bit of wheel spin at the launch? Couldn't see any on the first.
The only other interest I had was a view of the front lift. Not so much for the lift but for the lift to be level left to right. I've seen some still pics in the past that had me questioning that.
Edit:
Actually, if you look at the rear wheel well as opposed to the rear of the car, there is very little 'squat' from what I can see. And you're right, the car 'settles' back down quite nicely. I need to try to get the ASHAM8 module working again and play with different suspension heights. For now all I do is let it drop to parked height and shut off the air suspension in the trunk.
I'm still amazed how 'soft' the launch appears even with a low 1.8 sixty foot time.
