I will shed some light. 48" max is what I've found best to work and turn properly. If you go +3+1 like I did your to wide wide w a 3/2 off set factory wheel or most wheels people are selling. You need a 4/1 offset wheel or it bump steers and pushes horrible in corners. If I did it again I would go +2+1 for ease of having more then one set of wheels. Fireball has done me right with killer set up for years and replaceable rebuild able ball joints. They have lasted over 2 season of abuse without replacement. Most others use comst12 ball joints which once a year would need replacing actually everytime I jiggled a wheel one would be deteriorating . Best deal on the market Fire ball long travel arms.
