LSD Edgemakation
Trying to understand LSD's and their functions and how it functions on a track/racing scenario. From my understanding, the 1 way stock lsd will only work when on the throttle and not at all when off throttle (and when one wheel is in the air, it will not work). This means (to me... tell me if i am wrong) that only under hard acceleration will it function.
A 1.5 way would work when on the throttle and 50% when off.
A 2 way would be working 100% of the time.
What does each truly mean when on a track scenario. I have very little experience with RWD cars, but quite a bit with FWD, and I have never wrapped my finger around the true understanding of the LSD funciton and how it truly makes you faster.
Why is it that most of the LSD's for the s2000 are 1.5 way when "people" always say use 2 way for road racing?
Difference between (which right now looks to be my options)

ATS (Carbon & Metal)

The Torsen LSD needs 3 things to "work" :
1 - Difference in rotational speed between the (in our case) rear wheels.
2 - Both wheels need to have grip.
3 - You need to feed torque to the diff.
When you are off the throttle (and not braking with the clutch engaged / not pressed in), you're not feeding torque from the engine, but the kinetic energy from the car is converted into torque (because you are engine braking) and that is being fed through the diff.
So IMO it still works, on-or-off throttle, if all 3 conditions are there.
Going off the throttle mid corner would be such a situation, from personal experience (daily driving only!) I can tell that the S2000 handles that very well, you may get some reaction from the weight shift, but nothing violent.
