OK, so after performing Willards clutch type LSD test, I have concluded that I have some sort of clutch type LSD in my car. It's a '98 Spec ITR swap from Japan, and I'm pretty sure it came from Japan with the LSD because the previous owner of my car didn't mention an upgraded one. So my question is, what kind of LSD fluid should I use? Is KAAZ fluid safe for all clutch type LSD's? Mugen reccomends GL4 75W90 synthetic, ATS reccomends ATS gear old, KAAZ reccomends KAAZ fluid. I will probably tear apart the tranny this winter when I get a beater, and find out what is in there. Is there any easy way to find out? Thanks

all of the above.

 

I've been happy with the Redline MT-90. Motul products are excellent as well. Either use something with a friction modifier in it, or you can add a friction modifier to the gearbox oil of your choice: i.e. Honda MTF

 

is 20w50 alright to use?

 

I had good luck with Redline MTL plus Ford Fric modifier.....

Smooth, quiet operation with decent cold transmission feel.
