Pay attention during the driver's briefing. There is usually a supplementary session for first timers, often followed by some low(ish) speed sighting laps.
First timers usually start in group four, and this can be adjusted during the day (either within the group or moving to another group).
The most hotly discussed setup topic is tyre pressures, and there are innumerable opinions. My suggestions is...
Ask here first. Be very specific about the brand/model/size of your tyres. Some one will provide you with a good starting point.
On the day, after you have done all your preps, and had your first run, find people in with similar cars/tyres/etc and ask what their setup is. Most people will share, and the day becomes a social and driving event.
Also, some other tips for having a good day.
Get your times asap after each run (from Driver's briefing room), and ensure you are in the right position in the line up. If you get held up, stay calm. Don't feel pressured to overtake. Just ensure you are in front of them in the next line up. Be listening for the group call ups, or you will end up on the tail every time. You will quickly figure out the system, which is very efficient.
If you have a good chase with someone, go and introduce yourself. You'll both be buzzing.
Don't get too caught up in the technical aspects. Get your tyres OK-ish, watch what others are doing, and stay inside your ability zone. Don't overthink it. MX5s provide heaps of driver feedback, so listen/feel what the car is telling you, drive accordingly and you'll have fun without dramatics. Start slow and aim to improve a little each session. Focus on being aware, safe and totally in control and the speed will come as the confidence in yourself and the car increase.
Take plenty of water and don't forget to drink it.
Food is usually available at QR, but choice is limited.
There is air available at QR.
No fuel at QR. Nearest servo's are about 5klm away, towards Brisbane. If you don't have jerry cans, arrive with 3/4 or full tank.
The MX-5 crowd , and our non-MX-5 brethren, are a very welcoming bunch. The focus is on fun. I am sure you will have a great day.
