Since Season 2, the Formula E rules have allowed teams
to design and develop their own rear suspension.
There are now a number of different variants in use;
 we are going to look at a typical independent push-rod setup
used on all cars in Season 1.
Machined uprights house the rear axles and connect the
upper and lower wishbones at the outboard end.
Each side can move up and down completely independently
of the other, transferring loads through the push-rods.
Sitting on top of the gearbox are the dampers,
or shock absorbers, with interchangeable springs mounted
over the top. They support the weight of the car,
and control the weight transfer under braking and acceleration.
Their settings also determine how it handles the lumps
and bumps of a typical street track.
Machined rockers connect the shocks to the push-rods
and transfer the vertical loads seen at the wheels
into the horizontal forces managed by the dampers.
High-quality needle roller bearings ensure the rocker
rotates smoothly, even despite the enormous and
violent forces acting upon it, allowing the engineers
to accurately measure and fine-tune the car's setup.
Also attached to the rockers are links connected to
the rear anti-roll bar; the only part of the suspension
linking both rear corners of the car together. 
The anti-roll bar is fully-adjustable, and allows the team
to manage the roll, or how much the car leans
in the corners. Getting the whole lot set up to suit
your car, your driver, and of course the circuit,
is the key to unlocking the fastest lap time possible.
