You should have had an email with display instructions but in case you didn't, here's an extract:
Please ensure you arrive at the circuit prior to 09:30 and are parked by 10:00 (if arriving after 09:30, you may be required to park in the free public car park). There should
be NO infield car club vehicle movement between 10:00 and 17:00. Please do not leave until after 17:00 and note that you will also be unable to drive your car back into the event after 17:00 on any of the event days.
