Tightest Posi?
The only and I mean ONLY knock you can toss towards the Torsen is when placed under EXTREMELY high instant shock loads they can fail. As in 6k RPM clutch dumps on slicks. The way the worm gears transfer torque puts a spreading pressure on the case which can lead to trouble.
I personally have never seen a Torsen fail I have only read a couple of posts about it so take that as you will.
And Sam... I believe the original Humvee also uses a Torsen if I am not mistaken. No pre load either

The GM unit does NOT have springs, regardless of what the site says. Ok? I promise. There is a reason the T2R has become almost the standard for competition cars, because it works. Just works.

The Hummer diff is in the center, where you can't exactly unload one end. The truck can't just stand on it's front or rear wheels only. Very different than what happens with a solid rear axle.

Didnt the hummers have some kind of traction control/managment sytem too?
In fact wasn't the original Torsen developed for the Humvee? Maybe someone knows for certain I dunno. Regardless Torsen is quality built with excellent functionality.

What I did not realize is how bad people are saying it is in the wet. Are road racers (and autocrossers) forced to use a radical wet tire (like the Hoosier DOT Sports Car Wets) with a T2R in the rain??
AGREED. You have just as much a chance to shatter a 10 bolt ring and pinion with a drag race tire and the requisite 450+ rwtq and drag race suspension setup to do a < 1.5 sec. 60' launch, as you have to crack the T2R's case. But, as stated, that's NOT what this diff (nor a 7.5/6 10 bolt axle) is designed to do, so simply just don't use it for that purpose.
I'd put my money on the Torsen. The overall quality and craftsmanship is really evident to anyone who even looks at one of those carriers. Top shelf and U.S.A made all the way!
But i have to admit a lot of what i know about their goods and bads is what i have read in other posts on numerous forums online so take that as you will.
I use a Torsen and in my opinion Torsens are the best carrier option right now bar none especially for road/auto cross running.

My T-2R came in a Japanese lettered box. So I don't know
about the USA made bit.
Also don't know why people think the T-2R is bad in the rain,
other than what I said about being able to break both loose
and losing directional control as a result. But the same is
true of a spool or a tight clutch type rear. It's really on you
to drive below the adhesion limit (whatever the conditions)
or stick with a lower torque bias and have it done for you.
What is this rain complaint about?

Dang and I thought they were home grown
Only car I had that was scary in the rain was my a Big Block Nova but it wasn't from the posi...
It was a 12.5:1 compression engine with a Muncie and if you let off on the gas in the rain the tail would lock up
Especially dangerous at speed. That car was plain dangerous period. Old school early 80's tech with drag set up suspension and junko tires of the day ( as in slapper bars and drag shocks ) shouldn't have been on the street at all.

I don't have any plan on changing out the eaton though, and I'm guessing it's one of the reasons my 10 bolt is still alive.
