Alocking diff will prevent doughnuts, not assist them - you need an open differential to get one wheel to overpower the other for a doughnut, unless you're on wet / icy pavement...

.....or snow, or mud, or gravel........that's the point. Doughnuts are much easier if both of the back wheels are spinning otherwise you just end up with a one wheel wonder.
