Knuckles connect the three main components on a car: Steering, Suspension and
Drive-train. They are found behind the wheel connected to the hub.
Requires customization due to unique suspension geometry and customizable
steering. No Baja car is exactly the same and the more unique the better.
Topology optimization had been run on these knuckles to reduce the most amount
of weight without sacrificing strength.
With the new Baja SAE rules, all cars need front wheel drive. This lead to a redesign
of the front knuckles on our Baja car, to allow for transmission of power. While
redesigning them, the weight had to be increased, but with topology optimization,
the weight of the new one was maintained at the lowest it could be.
