Which diff fluid to use?

[Court M3]

Haynes manual recommends SAE 90 Duckhams D12001? Never heard of it. Anyone know what's the Redline equivalent?

For an LSD? I am using Redline 75w/90 with LSD additive and it works excellent.

i put the Redline 75w-90 NS in mine under the advice from RRT. it really chatters at low speed and tight turns (think parking garage). for a daily driver i'm not sure its the best choice. but when i get on the skinny pedal it locks up quickly.

I'm gonna use redline.
