First time at the strip for the Dart, results and what I should do for next time?

clamp the front segment of the leaf springs (stiffens the spring to plant the rear tires and aid in body lift) , more rear tire or try varying your tire pressure, if you have a front sway bar disconnect it, some 90/10 front shocks(helps transfer weight to the rear tires) and rancho/caltract adjustable rear shocks.
