Yanto in particular for driving the Ring, a few words of German can come in quite handy.
arschloch = asshole
fotze = womans genital area aka as in James Hunt
Fick dich = Fook you
Fick dich, Wichser = Fook you wanker
Wichser = you guessed it, wanker !
der abschaum der menschlichen gesellschaft = the scum of the earth (this one doesnt really roll off the tongue that well, so you may want to write it down and use it in the pits rather than whilst overtaking down through the foxhole !)
On a more useful note, take registration doc/proof of ownership with you.
You can tape up number plate at a trackday but sadly not at the Ring as its of course still a Pubic Toll road. Some of the more experienced Ring Stars will soon fill this thread will all manner of information ! What you have to remember about the Ring is, that anything you take down with you in the car,that you dont want to drive around the Ring with, needs to be left in a hire car if you have one, with a mate who isnt driving, or in the case of small children just tie em to a tree in the car park with some water and a packet of wine gums ! seemple !
