Default my99/00 wrx rear diff type

What type of diffs do the my99/00 wrxs have??

front open, LSD viscous coupling, what is the rear... viscous limited... suretrak... open...?

if say 4 wheels have no traction on this model will it just spin 1 wheel on each axle or will 2 wheels at the rear spin and 1 at the front ?

can't find much information for the ADM my99/00 wrx.

I believe the standard rear diff is a viscous open also. This enabled the cars to be more street friendly with turning etc.

I swapped mine out for an early model STi rear, 2 way mechanical LSD. It makes the car more predictable on the limits of grip and oversteer, however tends to lock up and clunk a bit for street driving if I have my centre/front diff locked also.

Front diffs are open...one can get various front LSD's including plated (clunky, noisy) or helical (not noisy - standard on Type RA V Limited).
I have an RA V Limited helical front LSD for sale if you're interested....see for sale section.

Okay so its like the one in this video? https://www.youtube.com/watch?v=w2bRb17jJ1U

looks like when one wheel slips the fluid heats up and rotates the other driveshaft,
probably helpful on sand and slippery surfaces.
so if i was stuck on ice would 3 wheels spin and one at the front no spin? (example)

for performance applications its an open diff.

had a quick look at this chart

http://home.gci.net/~cowdookey/818/T...art_Public.pdf

looks like most turbo models come with what is called a rear vlsd.
no ADM wrxs on that chart though.
