As said above, this is an event not to be missed, you get the chance to take your mkiv on track and can legally race it for the the day.
Its a great day out if you just want to spectate. If you have ever had an urge to try a track day but are worried about it, then this is the rack for you. It is perfect for the beginner and also some nice long straights, and for the more advanced driver there is the "bus stop" which is a nice technical part of the track where you can have some fun.
So don't just sit and wonder, Sign up, Pay up, and Race for the day.
