help with rear diff locking issues

[Ziger]

Hey guys, so i went drifting and im finding trouble trying to get the rear diff to lock up, i was wondering if it had something to do with the rear control rack, or what, if there was some sensors i could unplug to cancel the system, or maybe i blew the diff...i doupt the blown diff because both wheels still lock when i do a smoke show..

any help is appriciated thanks!!

Have you got a aftermarket 1.5 way, 2 way LSD or stock LSD, as they react differently. Sometimes the clutch? discs? in LSD need changing on diffhead, as my mate just did this not too long ago with his aftermarket LSD (setup for drift).

It probably would single spin (at least it did with viscous LSD on passenger side of my car) if it's failed. Basically no traction, wheelspin heaven on passenger side. Not sure if mechanical GTR rear diffheads are different in the way they fail.

i have no idea what diff it is, although i strongly believe it is stock because the car is very clean with no aftermarket parts except for nismo g attack s tune suspension, and a boxster computer. Both wheels lock when i "do a smoke show" but if i clutch kick while turning it does not want to lock, i tried taking out the anti skid fuse, and ima gonna try a lil test.
