I have no personal experience with them.
That being said, most comments I have seen on other forums make me unenthused about them.
The Honda folks love them, the VW/euro folks hate them. They seem to work well but don't hold up to low end torque.
My guess is the torque of the 3800 would kill it quickly.

Basically there are two pieces of conditioned metal presssed agianst the input and output spider gears in the diff. This is done by calibrated springs between the metal. Since the spider gears are pushing agianst eachother, it works to keep both the input and output spider gears spinning at the same speed. Or in other words to keep the wheels spinning the same speed.
I'm pretty sure they use conditioned metal like I mentioned but I know companies like Intense and Engineering Performance use clutch material between the spring loaded metal and the spider gears.
EP is another company to check out since they do sell LSDs for 4t60s.
But...
You may not need a LSD at all since many ser 1 L67s can get 2 wheels spinning all the time and have the tire tracks to prove it.

I used to think the same thing before I got my LSD. Definitely makes a difference if you are doing burnouts or if turning slightly during acceleration.

We had a 92SSEi run a Phantom Grip. He killed it in 30 days. (no longer a member here).

EP does advertise the 4T60 LSD'*, but nobody here has ever bought one. I was supposed to have one, but got screwed out of my money and the deal by a 3rd party, not by EP.

I personally think that until you hit the 13'* and want to go quicker, the stock diff is just fine.

back in the saturn racing days we had two choices for differentals. the $300 phantom grip and the $1000 quaife. needless to say most people ran the phantom grip, which also included in our case a new diffpin that was a hell of alot stronger and eliminated the only weak spot in the saturn transmission.

as far as the 4t60 goes, i can spin both tires on my L27/4t60E no problem, any time i want. so a LSD hasn't crosse dmy mind at this point.

The problem with open diffs in these transmissions is when both wheels are spinning very quickly then one stops abruptly when it heats up enough to have more traction than the other.
It'* generally not a problem for short dual stripes......short being less than 40 feet or non stationary burn outs.

Thanks a lot for the comments and thoughts... I'm brining the bonnie into the shop tonight(not for the diff)... it started with the intermentent hesitation with a good amount of throttle and now after a run it smells of gas in the garage...Checked for codes nothing... checked fuel injectors (good).... starts up like SH^% recently... swaped igniton coils (nothing) so we are depending on Downtown auto to fix whatever might be the problem.
