[torsen] Torsen 3

Torsen 3, if I'm not mistaken, is based on a planetary gearset and allows the static torque distribution to be set with a bias like 60/40.


Changing the static bias rate more to the rear would most likely mean changing out the whole unit as you would need to change the gear ratios.
I suggest sending Torsen an email for more info!

The other cool thing is that it can be packaged as a "twin diff", which packages the front and center diffs as one unit.#

You can not set a torsen to adjust more for the rear,
it sends torque to the axle with the most traction and
increasing the TBR will only make spider bite
worse...right, Scott?
