So I guess if they saw it when they check the car at registration, covering the timer screen or something to that effect would please the event officials? I got the feeling from the PCA UCR website they were very "by the book". The Audi club I used to run with didn't require anything aftermarket (like mounting a fire extinguisher) to participate. Feel free to mention any other surprizes I might run into when running with PCA. Thanks for the infomation.
