Just had a look at this series. Looks fun! What state is your car in MJ? Do you have to enter them all and roughly how much is it to enter?
How much track time do you get? I'm tempted by the croft one. My car is a 100% standard R26 Lux so I doubt I'm gonna set the world on fire! Haha
You need all fia gear, helmet, gloves, shoes & suit. Plus set tyres 1a or 1b blue book. Fire extinguisher etc
As Steve said you'll be better off on an open pit lane day with someone like javelin. I did my first last October and especially towards end of day I must of had the circuit to myself!
