I swear by Redline Synthetic fluids. Almost all the road racers I know run redline, with fantastic results.
Check it out.

I know most road racers use RedLine as I used to. The thing is my car is predominantly street driven with occasional autocross. I have owned 3 GSL-SE's each one having over 100k on the odometer. Everytime I have drained out the old gear lube and replaced it with a synthetic the differential eventually has gone bad within months... the noise! UGH. Could be that most road racers already have their diffs rebuilt..I dunno. Puzzled, I asked around.. spoke to rally car builders to the rebuilder of the 1979 24 Hour of Daytona winning RX-7. Both have told me not to use synthetic, it simply makes then go bad. Happy with I heard from them I now have cheap Valvoline mineral based lube in my differential. (:

I dunno know aobut that....
Synthetics are made from a pure basestock rather than taking crude oil and purifying to the level that you want.
Synthetics are designed to have far surperior lubrication qualities, there for causing less friction and longer bearing life. they also are much less likely to breake down under heat and extended use.

I know someone who uses regular ol' automatic transmission fluid in his transmissions and rearends. Puts some extreme pressure additive in the rearend for good luck, but that's about it. If you think about it, auto trannies operate under much worse conditions than manuals. Autos have splash lubrication (the pressure is only for the hydraulic controls) but they have much smaller gears/bearings and even worse they are usually encased in drums. Manual trannies/rearends are cake to lube by comparison.
Now the question I have is about the limited-slip additives. Do they make the oil "grippier" or "slipperier"? Makes a difference as to what type of oil to buy. Type F (old Ford) is the grippy stuff, Type 7176 (new Mopar) is the slippery stuff, and regular ol' Dexron/Mercon is in the middle.
I was going to wait until I personally did this before telling the world 'bout it, I'd feel bad if someone blew their ride because of bad advice. So this isn't official advice, just an idea that someone I trust is advising. Be it known though that I have a good stash of Type-F thanks to owning 70's Fords for most of my driving life.

Hmm I think I answered by own question.
Redline gear lubes should already be "limited slip compliant". Check the bottle to make sure.

I have heard that suggestion before. It provides superior lubrication and prolonged life for the gears right?

I use Royal Purple in my tranny and LSD diff - it doesn't share all the hype that Redline does but it's a very good product (and expensive) and includes the additive - The RB guys swear by it and I have a very quite tranny and rear end (except when I'm on the beans )
