Redline shockproof is a no in the gearbox unless you change it every 6 months. It gums up and causes hard shifts as it ages. I find either Penrite or Elf Tranself Synthese to be the best for S2K boxes. LSD (friction modified) oil in a Torsen diff is unnecessary, just use a nice 75w90 gl5 in the diff. I think they take 0.9L from the top of my head. Also check out our dimple magnetic drain plugs to keep your fluids super clean (see trader section)!
Oh yeah baby, Elf for your lubrication sexiness!
FYI: Yes I'm bias, but I've used Elf in my comp engines and daily, run sexy

I have used
oem = reliable but sluggish compared to other oils
castrol edge 5w30 = drank oil like crazy
liquid moly = 5w40 = hated being cold and cold days
motul 10w40 = responsive, didnt drink it
royal purple = responsive. doesnt drink heaps of it. dyno got 135kw and 160nm torque at wheels (didnt dyno before. mods inc js racing intake and hks hi flow axel back) i also didnt dyno on other oils so im not saying its because of the oil, the mods or a combo of none or all etc
this is jst my personal experience. i found no noticeable performances difference between motul and royal purple.
