Of course I did not mean any serious competition just gentleman like "sports driving". As you all know, it is not so serious when fins and swedes compete. Since we know how much better we are anyway... (Like 6-1 / 2011)
But seriously, one thing to check is that your insurance etc policies accept to drive with non registered cars on track at the same time. However, also our race cars should have "traffic insurance for off-highway vehicle".
Now I have to check if my N2O order has been delivered
