Some good advice there.
In terms of the car, check your fluids, park in gear no handbrake (heat will soak up the cable and boil your brake fluid), and most importantly come in one or two laps before you or the car is at the limit. If you kill the brakes by staying out too long you've ruined the day. Instead smaller, regular sessions are kinder on the car and you.
Building up is key especially if you've never done a TD or llandow before. It looks simple but it's deceptive.
Can't wait, weather forecast is dry and cold at the moment
