Because Honda has made like 3 rwd cars ever and doesn't know how to build a stout rear end.
What does Honda's experience have to do with the differential in the S2000? Your comment makes it appear that you don't have a clue what you're talking about, becuase Honda did not design the differential; Honda did not design the gears inside the differential; And Honda didn't even design the LSD.

So, Einstein, where is the space warp that connects Honda's esperience to the S2000 differential?

However, the Torsen isn't necessarily the best choice for every application. When one tire loses all its grip, the Torsen will let it spin, and with the S2000 and R compound tires, the inside rear tire can unload and spin freely.
Hmmm. Do you think this contributes to the hydroplane oversteer crashes? If one rear tire hits standing water, you'd get MORE spin to that wheel through the LSD.... wouldn't that be unpredictable and difficult to control?

Must say those are some really good explanation of LSDs. I've read them from various places like Wikipedia and How things work, etc. but this is quite comprehensive!!!!

Don't underestimate Torsen.
They are way ahead of you all
Torsen T-2R
(best of both worlds I guess)

About the diff, Honda didn't design the 7" ring & pinion, and the Torsen LSD unit is from Torsen.
But all Mazda MX5 (Miata) diff housings I have seen online don't look like "ours".

Are there pictures of "our" diff housing used in other cars?

IMO: the S2000 is a "track designed" car and on the track one needs to be smooth, no shock loads, etc.
The OEM diff, with the proper oil , can take that no problem.
I wonder what oil penguins2001 used.
(please let it be a single grade SAE 90 GL-5 )

Oops, I missed that question.

SpitrireS, I have never seen an S2000 diff in anything but an S2000.
Have you?

if someone would explain what's the difference between 1, 1.5 and 2 way LSDs - he'd be my personal hero forever

I'm too lazy to try to explain it, when I can just steal this from the KAAZ Web site.

Some manufacturers make LSD's in different configurations and are commonly classified as 1 way, 1.5 way and 2 way. This designation reflects the design of the cam groove which enables the LSD to function differently under different loads. A 1 way differential means that the cam is shaped in such way as to have positive lock only when accelerating. The 2 way is constructed in a way to have positive lock motion in both acceleration and deceleration mode (Figure 3). The 1.5 way functions almost same as a 2 way but provides less lock when decelerating. The 1.5 way can provide more forgiving balance when braking than a full 2 way setup, although it is less effective for true racing applications, it provides easier operation for beginners in throttle off conditions. 1.5 way is also very effective for front wheel drive cars which need extra stability during braking.
As an interesting side note, a diff like the KAAZ can be reconfigured, so if you have a 1.5, you can change it to 1.0 or 2.0. The 1.5 setup is the best choice for most applications and driving styles, including drifting.

i wonder how the diff helps while braking... i mean rear wheels are pretty much in the air under hard braking. so does using 2 way diff mean there will be a bit less squirming and less course corrections needed under heavy breaking?
