Pull Rod & Push Rod suspension

[Duke]

Some of this still went over my head, but below is a great article on pull vs push rod and how Red Bull had to change their car to fit in the double decker diffusers - and just how big these were in 2009/10 compared to what the rules were intending them to be.

We put a lot of thought into pull-rod vs. push rod in Formula Student. Aerodynamics aren't an issue there, so it's all down to CofG.

In the end we went for push-rods for simplicity, conceding that pull-rods kept the weight low. But it's certainly not night and day. Pull rods get the springs and dampers lower in the car, but they require stronger top outer joints and upper arms, placing weight higher on the uprights, and more unsprung mass.

Always wondered what the big deal about how the pull rod suspension was / is so effective, and that article really helps to clarify a few things.

Interesting that Lotus will be going that route next year too what with them buying the Red Bull gearbox & hydraulics setup now.
