Test parts, Test Software, Component Changes & Set-up Changes

In Simple Terms

Teams can test new parts and software during official tyre tests, but the car's basic setup must stay the same throughout the test. They can only make changes to the car's mechanical setup, driver controls, or software if it's absolutely necessary to properly test the tyres or complete the test.

• Test parts and test software are allowed during tyre tests
• The car must maintain a fixed specification, configuration and setup
• Mechanical setup changes are only permitted if necessary for tyre evaluation
• Any component or software changes must be justified by tyre testing requirements
