Are beadlocks necessary on the front of dirt sprintcar or will non beadlocks hold the tire on the wheel enough on both corners? Also what offsets are preferred?

Beadlocks aren't required on the fronts-you only need them if you bang wheels alot. If you do run them, make sure to run the cover on them, otherwise they just trap and hold all kinds of mud and make the wheel out of balance. I run -3 off wheels on both sides, some run -4 off on right ft. That's for a 50" axle in a winged car.

4 rf and 3 lf, or a few run 3 on both, and as far as beadlocks go its a preffrence
