https://www.circuitcat.com/en/experiences/circuit-series/ Track days: 59.40€* Circuit Members: 44.00€* The participant’s insurance is included in the Track Day price. https://www.circuitcat.com/en/membership/ Various levels of membership, but all include discounted entry and grandstand tickets for F1 & MotoGP amongst other things. Seems like a bargain compared to what Silverstone demands.
