Guy's I have been fighting a wheelhop issue for a while. I run a set of Caltracs and the guys at Calvert have went above and beyond to help sort it out. Heres the deal I run a detroit locker no clutch type but a gear to gear like is used in nascar racing. I think this may be the problem anybody else run one? It will do this with street tires drag radials and slicks. If the track is greasy it seems like it goes away because of the lack of bite in the track. Just looking for the cure!!
