Cost!! you can remove and replace the trans in about 3 hours with hand tools,,just the limited slip requires special tools and is not a do it yourself, as a rule. That said I just put a limited slip box in the car and WOW big change, on the track no more one wheel peel out of corners and stable hard braking, not 100% sure why on the braking, but I know it stopped squirming.
AOR transaxles also have harder first and second gears.

It is if you play nice!

I had to have mine rebuilt a couple of times before I got the Motorsport one. I wouldn't say I dump the clutch etc so I'm happy with the stronger version. Not sure the OEM one was designed for more than fast Autobahn driving?
I had a factory one shimmed up for more lock ..
I would expect as it would slip less it would take a little longer to wear out
you can test it with a torque rench there is a given break out torque for given lock ratio i believe..
there was also i good thread on here if you search saying that they will perform differently according to the oil used in them .
it basicly said you build them a bit tight put one type of oil in then when they start to slip a little you change to anther kind of oil and they get grippy again and you get another little bit from them befor pulling them out to service
I installed a Guard this winter. You don't want to tackle the installation of a $2,500 part in your trans unless you're pretty damn proficient and have the tools and shims. You further need additonal cooling if you expect to run sessions longer than 45 minutes. Removal and install are the straightforward.
