Lancer Evo in japan comes with an electronic center diff. You can control the torque to the front or the rear wheels with a turn of a button. Meaning that you can have more power to the front or rear wheels to create a biased distribution of power. GTR's came with this as well. Im not to sure if the WRX has one but i know that the EVO and GTR are have it as an option.
