jdm transmissions

[Samiam1017]

I'm looking for a 4.11 geared trans and seem to get lots of replys on jdm transmissions. I thought I read somewhere that they came from the factory with a front LSD. Can anybody help with this. Thx

Perhaps off-topic, but with my STi USDM six-speed, I was wondering if a 4:11 ring and pinion would be readily available to fit it?
I see three "75mm split-case" six-speeds for Legacys at the end of Rallispec's list (thanks) and wonder if their ring and pinion would be compatible? I already have a OS Giken diff for my tranny.
Aftermarket? I only see this from Rallispec:

RST-1909
STI Front Final Drive Gear Set 4.44
6MT
$1904.00



PS: they have it for the five-speed at an incredibly low price (in comparison):

RST-1907
Subaru Front Final Drive Gear Set 4.44
5MT
$324.56

My donor ended up having a 05 2.5RS transmission, It has 4.111 open dif, I just go carted at an auto-x and I would like to get rid of it for a 3.9, preferably a 3.7. I run out of 2nd gear at 55MPH.
