unfortunately guys, the d-series has no love when it comes to LSD, 2 options really, M factory or Quaife

if money is tight than mfactory hands down, if not than quaife ftw

than there are alternatives ....... hrmmmmm ..... phanton grip lsd (not a true lsd) or OBX lsd are the dark side, cheap for a reason, they are just plagued with problems or worse leads to blown trannys/diffs, plenty of stories online
