SF products for Subaru WRX STi

[kwantam]

A quick question to make sure I'm not smoking crack:

I'd like to use SF products for the transmission/front diff and rear diff in my WRX STi, and I've heard good reports on the MTL-5. However, it is specifically recommended that this oil not be used for separate final drives. My rear diff also requires a GL-5 75W90, so I'm assuming this means I want to use HDS-5 in 75W90?

Thanks in advance!

I have the Saab 9-2X, essentially a Subaru Impreza wagon in nice clothes. I have SF MTL-R in my transmission, it's WONDERFULLY smooth compared to stock. I don't know how much different your gearbox is than mine, but, I imagine it's not THAT much different. And, yes, the HDS (or something like that) goes in the rear differential (although I don't have that in mine...yet!)
