Differentials

[joevenzon]

Thanks for the input. The open and viscous coupling types are supported in the current refactor code. Viscous coupling is a type of speed-sensitive limited slip differential, and an open differential can be simulated by setting the anti-slip parameter to zero. I'll read up on the torsen and see if it's at all similar to an epicyclic diff with speed-sensitive anti-slip.

From some reading I did today, the Subaru Imprezza uses a viscous coupling center diff (50/50 torque distribution) and a viscous rear diff, so should be covered there.
