Hi Ian and welcome
Just turn up on the night mate :-)
Some one is normal there by 5.30 and booking in is by 7pm
If you get there earlier then you can practise and help with track.
Make sure you got some form charging cause there will be practise, 3 rounds and a final to race.
The club will surply a hand out transponder for each of you that will count your laps. You will have to make a small hole in your shell were it clips to.
We will sort that for you all on the night
As for crystals this maybe an issue but at worst we can put you all in same race together.
And if you want cup tea or coffee bring cup with you.
And don't worry mate we are a very friendly bunch people
Cheers
Jason A
