Hi Mark,
Pleased to welcome you to the club. Don't worry about asking something stupid, we all came to the club with so many unanswered questions. Feel free to ask away, there is a wealth of knowlage out there. Hope you are able to come down to Goodwood for our trackday on Thursday 17th August. You can ask as much as you like and you may even get a passenger ride for a lap or two !
