What for? The OP just needs to verify what he has. With an open diff, out of gear it spins in the opposite direction.

 

or it will spin the driveshaft, with a vlsd it will also spin the wheel the oposite direction.

 

The vid doesn't show that. I have to jack up my car tomorrow to adjust the diffuser going to check it out while I'm at it.

 

Ok, last night I jacked the rear end up and the tires spin opposite ways. However, I did not try it while it was in gear. Didn't think about it at the time, however I don't understand how it would be possible for them to spin in opposite directions when in gear?

 

You have an open diff. I just tested out my VLSD while adjusting the diffuser, wheels spin in the same direction out of gear.

 

ok, thanks for all the help. What is the downfall with the open diff? I seem to be hooking up pretty good when launching hard, unless I'm a hell of a lot better driver then I give myself credit for lol. Also what is "diffuser" I have heard mentioned multiple times.
