Need Advices to Setup Rear Suspension

Actually looks like a pretty decent launch but some on here talk about Squat.squatting in the back means you're not transferring the all of the weight to the ground some of it was absorbed by the springs. you actually got lift the moment you left the line in the rear which indicates is pushing down on the tires and up on the body which is what you want however the more the body lifts in the rear the less it plants the tires. just my opinion don't know if that helps. What was your 60-foot time
First thing I`d do is get those "4 speed" slicks off it, and put some regular 10x 28 hoosiers, or M/T`s on it !!
