The task was to design a suspension setup for a car to race around the Indianapolis 500 Motor Speedway. The track was modeled 1:5 and the design needed to model a steering function.

 

The design consists of a double wishbone suspension setup with a spring/damper extension as a single unit. The rear setup consists of hinge connections between the wishbones for vertical movement only. For the front setup, a ball joint was used to account for a steering rod to allow for the rotation of the tire around the vertical axis. Also, the front upper wishbone was shortened to give the front tires a negative camber of about 1°- 2°. 

​

The wheelbase length was extended for better stability on turning as well as larger rear tires to improve acceleration with a larger contact patch of the wheels. 

​

As a result, the car was only able to turn around the first corner. The suspension held was able to keep the car stable and with the negative cambered front wheels and banked track, the car didn't lose grip and slip out.
