[Advanced Design]

The spindle arms could probably be swapped left for right. I would guess the spindle arm mounting surface, going against the aluminum, was machined smooth for a more consistent and stable mating surface. And the exposed surface on the opposite side isn’t. Just theorizing on my part.

The interesting question is why did DSE develop and produce them this way, with the tie rod ends pointing up? Maybe something to do with keeping the tie rod in the same plane of the center link at typical vehicle weight and dropped ride height? Or more likely it has to do with their Speed Max system that is complete from their own designed suspension crossmember, through a steering rack and out to the brake rotors.
