come on man....i really really dont know why the factory fitted LSD is so highly regarded - i mean..come on.. we arent exactly drifting our sportages- and well...actually...they suffer fom a very serious lack of power- so who cares if they tend to spin a single wheel??
as for off roading- as i said before- mine has a perfectly good lsd and i really dont feel its advantages when going off road. meanwhile - i had a chance to drive a friends vitara (suzuki sidekick for you guys in the USA) with a rear auto locker- now THAT really works.
