Open diff applies the same torque (50% to each rear wheel) regardless of traction. Not good on a track when you're powering through a turn on the edge of traction

VLSD can transfer torque to either wheel as needed. This effectively allows the car to put down more power to the wheel with more grip, maximizing traction, typically during a turn. Of course the VLSD isn't a proper track solution - the fluid overheats way too easily and it just turns into an open diff until it cools down.

A 1.5 or 2 way diff allows a lot more torque transfer and is ideal for track driving.
