I thought the website would have more info but it didn't and I didn't make a better note of the specs as I was looking for 75w85.
OP is in Denmark. Might be a little hard to get.
I'd suggest the Red Line MT-90 as someone else did. It's a 75W-90 GL4 that's supposed to help with synchro engagement and to prevent synchro wear. I had good results with Red Line MTL (70W-80 GL4) that was recommended for a Honda manual transmission that specified 10W-30 motor oil.

I used Motul Gear 300 in my 2004 WRX, but after my reverse bombed the guy who replaced the gear (and I've never heard of this happening to anyone else) probably just used an off the shelf 75W-90 GL5. The toughest part of that was finding a T-70 Torx bit to remove the drain bolt. The first time I changed the tranny fluid in that car, I used Red Line 75W-90NS, which was their version of a GL5 gear oil without any friction modifiers (generally a requirement for GL5) to make it more slippery for LSD use.
Back in 2005 I bought the Gear 300 for maybe $9/liter. I got it from a motorcycle parts dealer that also had Motul DOT5.1 brake fluid in 500 ml bottles. I ordered a reasonable quantity for my car, but they guy taking my order over the phone was asking why the heck I needed so much, and I said it was for a car. They actually sent me the wrong brake fluid (Motorex DOT5.1 250 ml in cans), told me to keep it since it was their mistake, and sent me the Motul brake fluid. I was also told that the guy I talked to did inventory and noticed less of the brake fluid than they thought they had.
