i heard powerzone do customized LSD..maybe someone can ask...
*in japan, they use LSD/4WD during winter time where snow is covered up the street. the normal car has to chain their tire if need to drive.
and of course rally drive will equip any best solution for their handling. in our case, for road use, what for?you might suffer the power steering features..gti when use firm suspension with bigger front/rear sway bar..
