Just remember that locked difs are illegal for street use. Have you ever wondered why?

Also, if you lose it in the wet as a result of having no lateral [sideways] traction, & you are involved in an accident, your insurance company can wipe you like a dirty, ... ummm ..... rectum. Cars that have been deliberately modified to an "unroadworthy" spec are not covered by the policy. Just something else to think about.

Go the spin resistant type LSD, & be carefull in the wet.
