I don't think so. Remove the restrictions on the F1 cars, they will go faster.
What restrictions do you think they're using?
They're designed to use 10/10ths of the rules. Nothing more, and nothing less. Saying that lifting the restrictions would allow them to go faster implies they over-designed somewhere, or left potential on the table. That's not something F1 designers do.
