I have a 93 mustang 3000lbs with me in it, I have 325/50 drag radials on it right now.(car is minitubbed) Looking at putting on a 28x10.5w mt drag slick, a hoosier qtp 28x13.5 I have billet specailties street lites on it. Im trying to lower the rotating mass due to the radial and rim combo being a little on the heavy side. I never got a good 60' on the radials(not the tires fault, they were just a few years old) I know the street lites are heavier than most wheels but there is also almost a 10lb difference between the radail and the slick. Just need some direction! Thanks as always everyone!
