are you going with a 1.5 way or 2 way?
the stock unit is a gkn viscolok which is speedsensing (you need a spinning wheel to lock the lsd... slow, not perfectly predictable/direct).
the os giken is a torque sensing clutch type lsd which acts and reacts way quicker.
i will start with the standard ~1.7way os giken type-s setting and try it. if i am not happy i can switch the center unit to 2 way or flip some discs (in standard setting only five out of seven discpacks are "active").

after the os giken i will try a drexler unit and compare both. drexler is the unit of choice of most european motorsports teams.
