Just to complicate things further, some cars can use the differential as part of the traction control system. BMW's active differential comes to mind:

This is probably massively overkill for your standard home grown racing game, though.

Actually I want to find out the maths behind this. It seems like something very interesting:)

Very interesting! It looks like a regular clutch-pack limited slip differential, but the "active" part in the M means that the clutches are engaged "on demand" by the electronics, instead of as result of the mechanical action. Since I've already simulated the LSD differential, it would be very easy to implement an active differential like that. The difficult part would be emulating the logic behind the electronic part in the different situations.
