Drive Train--limited slip front diff of a 4eat

Has anyone installed any kind of a limited slip in the front diff of a 4eat?

Aliens existed before this, that's how rare it is.

I haven't seen a front LSD anywhere for an AT front diff.

Sorry, meng! It's not like it can't be done, though.. just probably not for an AT. Any reason you don't want to go 5MT? With that, you could look into Cusco --a very well-known and respected performance parts outfit. However, they're more than spendy --Cusco parts tend to be small fortunes, however, I'm sure they'd have a front LSD for you.
What about STi parts?

The 4eat has been built up so the shifting is fast and
reasonably hard.

Even on dry pavement the front wheels occaisionally
slip a little. Colder weather and wetter roads could become
interesting, so I'm looking to reduce wheelspin.

This seems more important than concerns about a lsd
pushing understeer on a track day.

Spinning wheels on dry pavement is not good for the AWD system.

I'll have to have a serious talk to my right foot about that.

I'd suggest you do that. If you don't, you may end up with a mangled AWD system resulting in a car that won't move.

It's an auto....you don't have direct drive to anything.....so as long as there's good ATF fluid in there, and it's changed often.....he should be "ok"

I floored my car in the wet and couldn't get one wheel to spin. I don't have a turbo, but even still, if I floored it and couldn't get a wheel to spin, there must be something wrong with your car.

Josh - What do you mean that an auto doesn't have direct drive to anything? Isn't the front differential's input shaft connected directly to the transmission's output shaft?

Again...sorry for the confusion...must have been one of those days.

I was commenting on Manarius's comment about spinning tires on AWD cars.

My comment was mainly directed towards the fact that the torque converter uses fluid as a medium between the engine & tranny. But that really doesn't mean squat because the tranny still takes abuse......so disregard my comment.

Hehe, ok. :)
