Some good advice - but a lot of it is aimed at (or for) seasoned track day people.

As this is your first one ( I presume) you will be taking it steady, but checking over things like brakes and coolant is simple and a good start.

Re the DOT 5.1 fluid, check out the boiling points before just buying any, as there are many DOT 3 or DOT 4 fluids that far exceed the DOT 5.1 stuff. Higher DOT numbers dosn't always mean its better.

Just get out there and have good safe fun at a speed you feel comfortable with, don't be put off by others going faster (or slower).

You should aim for getting a full days sport in at a pace you feel happy with rather than just 5 blistering laps and a knackered car.

You should come away from your first one with a list of jobs you want to do to the car to make the next one even more enjoyable, not worry about the next six months paying for it... as you never know you might find its not for you and all that money spent upfront is then wasted.

Im sure you will love it - and have fun but dont go over the top just yet IMHO.
