What is the difference between a Helical gear type LSD & a Multi-plate clutch type?

The clutch type has several small clutches in the centre which are in constant contact; this allows the wheels to have a small difference in speed but not much (ie limited slip).
The helical gear LSD does the same job using a complex array of helical gears which I don't really understand. Maybe someone smarter than I will explain how it works.

I'm not really after how they work, I've got a similar understanding to you, Norbie.
I'm more after info on which works best in what situations.
TRD has either listed for my car, but they're only $40 difference in price (mind you $1240 & $1280)
I'm glad I got at least one smart-arse comment on this topic

The helical gears are basically like worm gears - when there is a speed differential between the 2 wheels, the worm gears intermesh and tighten thereby limiting slip. Look up "Torsen differential" in google for a better explanantion than Dave's diffs 101.

From my limited understanding of LSD's, the torsen is considered superior for a road car as it applies torque to the slipping wheel almost instantly, and it has the added advantage of containing no wear components (like clutches). Torsens aren't very good in extremely low-grip conditions (eg ice) or situations where you're likely to be lifting a wheel (eg extreme offroading). If one wheel completely loses traction, the LSD function of a torsen won't work at all so you essentially have an open diff.
I'm going with a torsen LSD because I can't imagine I'll be driving on ice very often (I live in Queensland) and I have no intentions of going offroad in my Supra.  Clutch type LSD's are notorious for wearing out the clutches quickly in high-power situations, and since I have a 400hp engine in my Supra the torsen seems like a more logical choice.

Depends exactly on what you want it for - a good clutch type can't be beaten for those of us that like to treat our cars in ways unimagined to the Taliban, whereas the Torsen is a great all rounder, which isn't full of clunks and surprises, and will last almost forever, unles you actually snap it

My torsen wnet bang and now I am scared to replace it, too much $.
Clutch type diffs are for girls ( well after 2 months behind a decent engine they are!!)
get a minispool or CIG locker and "FEEL THE G'S "

Broke an axle as well !!
Got the CIG locker atm, trying to put up with the other considerations that go with having this diff.
Carry a spare axle now too.
