OK great - thanks James. We'll chat about it sometime. I don't want to make new tyres compulsory - we've all got plenty of half used sets which will probably last half a race anyway but I'm sure some ppl will want new tyres. This is mainly for fun and to get a few extra people involved although of course any regular drivers that enter will be favourites

What I really want to some of the hobby karters and myKart guys to enter - a lot of them have got Rotaxs - and get a comparison on how they are compared to the regulars. Maybe it will encourage people to join RMC sometime....
