- The go to option for suspension when it
comes to ultimate performance has and
probably always will be the double wishbone
suspension system.
While this adds complexity, particularly in 
a road car application, when it comes to
outright performance for racecar application,
the double wishbone suspension provides
the engineers a lot more flexibility in
terms of the suspension pickup locations
and aspects such as the camber curves as
the suspension moves through its travel.
When it comes to the ultimate in racecars,
open wheel racecars such as Formula 1
and Indy Car, the other aspect that's really 
important is the aerodynamic performance
of the suspension.
Here we can see the wishbones that are 
part of the suspension system are all profiled
so that they produce the smallest amount of
aerodynamic drag as the car moves through
the air.
This becomes particularly important when these
cars are exceeding 200 mile an hour.
Another part of optimising the aerodynamic
performance of the suspension system is
removing the damper and coil spring 
arrangement from the air flow.
This is done by using what's referred to as 
a push rod suspension system.
Here, a push rod runs from the lower side
of the hub assembly all the way up into
the bodywork.
And the coilover, along with the spring,
is fitted inside of the bodywork,
getting it out of the airflow.
