Need Advices to Setup Rear Suspension

I went back and look at your first 2 videos and the front isn't getting much rise under launch.
I think that you need more travel up front.
See how the wheel well all most covers up the top half of your rear slick? The top of the front wheel well molding should cover at least half of the rubber of the tire.(taking about from the top of the tire to the rim) HOWEVER, if you drop the front that much, you will need to have it re aligned or at least re set the toe.
