Is VLSD in Sport Package really useful ?

As the internal fluid breaks down, the limited slip effect becomes less and less. At roughly 60k miles (lots of variables, but that seems to be a good rule-of-thumb figure), you don't have much LS left.

Thanks for the explanation.

Until now I've done my best for all maintenances, and now hitting around 130K miles, I believe I must have gotten the VLSD fluid changed whenever needed.

Then if the fluids were changed properly, is it pretty useful for street driving? (I don't go to a track, and mostly I drive very mildly)

the fluid for the actual LSD itself is separate from the differential fluid that you drain from the differential. basically once the fluids in the LSD break down you have to get the LSD rebuilt

Then now my VLSD is useless even though I've followed everything on the Nissan maintenance guide ??

If yes, then it does frustrate me .. OTL

Time to upgrade to Cusco LSD.

Wavetrac for DD, and track. The more track time. Then Cusco or OS Gekin, which you can tune.

Think of it as a wear item like your clutch.

There's some great upgrade options out there =)

Love my OS Giken! The aftermarket stuff requires a little more maintenance.

I thought its oil was wear item, so I followed the maintenance guide to get it changed whenever needed.

But I didn't expect the VLSD itself could be a wear one.

So you're sayin my VLSD @ 80,000 miles and 10 track days is prolly not LSD-ing anymore?

If what the others are saying is correct, then your LSD is about done.
Vote Cusco!

Mine goes south after about 10 to 15 minutes on the track. After it cools, it will come back.
