    Could you guys please explain to me how does lighter/thicker differential oil effects the car ?

    Thanks!

    The lighter it is, the more movement the differential will allow.
    The thicker it is, the less movement the differential will allow.

    Thick fluid is going to send power more evenly from tire to tire or front to back depending on which differential it is going in.

    Light fluid is going to send more power to the tire with the least traction.

    Thick fluid effects turning radius due to less differentiation between the inside and outside wheels.
    Whatever it is I just typed... could be wrong.

    Hmm... so if I want tighter turns with more grip I should go with a lighter fluid (for racing)? and if I go with a thicker fluid I'll cause it to lose control more (more of a drifter)?

    Tighter turns = lighter fluid
    More grip = heavier fluid

    For racing, I see most have lighter fluid up front than in rear... and quite a difference.

    Full on locker... there is a fine line between too thick and thick enough; and it is different for every surface and driver.
