the locker and the transmission are the two biggies for me. after researching the Off Road standard equipment, I found better aftermarket alternatives, anyway.
however, I wasn't able to find a way to replace the locker aftermarket.
also, I'm really wanting a manual transmission and most of the X's here in Denver are automatics. From my research, it's not trivial to convert an auto X to a manual X, like it is with other makes/models.
