Default Rear 2010+ LSD Check

Has anyone tested the rear lsd check by lifting the rear diff up (both rear wheels on the ground), and moving the tire one way.

Well today, I tried this and while moving the tire one way on one side, the other side rotated the opposite. I've found that on my previous cars, the wheels will turn the same way when equipped with the factory helical lsd.

Has anyone with 2010 rear carrier tried this?

Torsen limited slip is supposed to do that. My S2000 did the same thing with its LSD.

+1. Torsen is a torque bias ratio differential. If you have one wheel unloaded, it will act just like an open diff. Only the clutch type LSDs rotate in the same direction.

Sorry but does anyone have the differential code from their build plate to suggest torsen fitted or not. What I mean is on the Supra it is B03B (differential torsen) or A03A (open differential)

58J I took pic of mine due to paranoia. Looks like it was manufactured late 2011.

Awesome thank you, so I am looking for 58J on the data plate, my 2010 arrives in Feb so I just wanted to know what to look out for.
