how does aerodynamics affect suspension in formula car?

[shrikkanth]

can someone explain how the aerodynamics of a car affect the suspension in a formula car. and what is the difference between the pushrod and double wishbone suspension?

Double wishbone suspension only works with pull rods because otherwise the aero load will multiply by pi into your lower control arm and the bending load induced by you sticking your pushrods halfway between your ball joints will break the poorly fused welds on your solid steel control arms.

Aerodynamics will make your car faster, no matter what. Don't worry about the negative effects, because they are negligible. Just build wings and put them on the car.

With a pushrod suspension you use a shock absorbed, because shocks look pretty on race cars. But a double wishbone suspension doesn't use shock because shocks are heavy and teams just weld wishbones that flex to the frame to allow the suspension to move.

Hope this helps.

Please read the "if you are new here..." thread. Chances are, someone's asked the same question you have...

Also, if you ask stupid questions on the forums, you WILL get stupid answers. Do some research before asking your questions.

Go with a McPherson strut suspension, it works best with aero. as for the aero itself, We just water-logged some plywood and molded it into a 45 degree curve and strapped it to the top of the car. Instantly cut our lap times by 50%.
