I have an R32 gtst, and im trying to get more traction from the diff.

It tends to spin the inside wheel when pushing hard out of a corner.

So does different oil effect how the vlsd works?

Or is it this:

Viscous LSDs are less efficient than mechanical types, that is, they "lose" some power. In particular, any sustained load which overheats the silicone results in sudden permanent loss of the differential effect.[6] They do have the virtue of failing gracefully, reverting to semi-open differential behavior. Typically a visco-differential that has covered 60,000 miles (97,000 km) or more will be functioning largely as an open differential;[citation needed] this is a known weakness of the original Mazda MX-5 (a.k.a. Miata) sports car. The silicone oil is factory sealed in a separate chamber from the gear oil surrounding the rest of the differential. This is not serviceable; when the differential's behavior deteriorates, the VLSD center must be replaced.

Which means: get a new diff centre.

Thoughts anyone?

Viscous cartridge is a sealed unit, separate from the diff oil. The diff oil is only conventional diff oil, because there's nothing in there that it touches that is supposed to have any more friction than an open diff.

The only fix for your diff is to bin it in favour of a diff that is actually an LSD, given that I refuse to classify VLSDs as LSDs.
