Kinematically, push/pull-rod are equivalent: the wheel can displace in the same way with both configurations (meaning that, as the car goes over a bump or the tyre load changes due to load transfer, the wheel changes its camber, toe, etc., in the same way)

But here's the catch:
- Constrains (aero, clearance, mechanical stress) might prevent designing a pull-rod that behaves like the previous push-rod;
- Compliance (carbon fiber is very stiff, but it still deforms!) can change that further;
- The impact on airflow is significant, and sometimes unpredictable.
