Hey mate, before Silverstone this is what I did.
Keep up on your fitness:
Make sure you are hitting the gym 3-4 times a week. Work on your muscle endurance and also your cardio. Lots of running and cycling. Now is the time to push yourself and get those last extra gains. in the 3-4 days before leaving for Silverstone, have a break and make sure you get plenty of sleep. If you get time (which we did) before Race Camp starts, go for a easy run in the mornings (but be careful, make sure you know what you are doing that day and act accordingly. If they haven't told you what you are doing, expect the worst.) They will do an initial fitness test before the Race Camp starts also, so be wary of this. As soon as you get there, water is your best friend. Always have a water in your hand and always be drinking. It's good for the judges and instructors to see also ;-)
Do some real driving:
Go to a Nissan dealer and tell them what you are doing and where you are going. If you get a good one, they will let you take a 370z for a test drive. Make sure you get comfortable in the car and make sure you know how it all works. Make sure you take a manual for a drive and not an auto. Get used to the clutch and the gearbox.
Apart from that, try and drive as many different cars as you can. Also try and get out to a track day or do a motorkhana event. Get as much time behind the wheel as you can.
Do those things and you'll be as prepared as you can be.
But in the end have fun. Race Camp is a once in a lifetime opportunity that money can't buy, remember that!
