I run an NB8A as well, under the bonnet is standard but over the past 2 years I have added things as I go along
You DON'T have to be fast, you will be placed in a Group based on lap times, someone doing their first ever would be placed with the 'slower' drivers, and after that should you prove much faster you will be moved up in accordance
There will be plenty there that will be only to happy to give you any assistance and tips you require, no 'sheep stations' just lots of fun, some are damn fast [Group 1] others 'almost fast' and others that prefer to learn technique, cornering, corner lines etc
Overall you will have the BEST day with a great bunch of people

See you there
