(VIDEO) Suspension HELP for 70 dart swinger drag racing!

wow. thats a difference. what did you do exactly ( in simple english please ) ? my car launches like a parallelogram means it goes off the supension rear and front same time. i race 4 times a year so i never paid Attention that much but now that i see this comparison I am exited to make some Progress on my 2sec 60 ft time....
main difference between the two videos was tightening the rear shock and moving shock mount (back to stock fixing my mistake)

What do you have for shocks currently? Caltracs?
