If anything a properly setup bag job will decrease your body roll, and help with your launches at the track. Thats assuming that the rear suspension is setup properly. My personal truck has bags on it with 4link and hooks very well at the track. We did speedaddicks truck on here with bags and he has a built 5.3 running 10psi of boost with 265/35/22s in the rear, he can't spin the tires launching on the street.
