I have a friend that races karts, here are a few links he sent me just incase anyones interested. I think this would be a lot of fun to get into.
http://www.ekartingnews.com/ Major online source for information
http://www.ekartingnews.com/forum.php There are a number of forums you can check out Shifter / Rotax etc….
http://www.ekartingnews.com/media/main.html# Some video. Check out “Part 2 Another Day with Memo”. That’s Memo Gidley (Indy Car driver). Also there’s a clip of Eddie Lawson in his Super Kart.
http://www.rmaxchallenge.com/ This is the series I run. The class is world wide each country has regional races that go to a national event then the top 3 from the nationals get an expense paid trip to the World Finals. This year I think they are in Malaysia. Pretty cool class. Very cost effective and lots of good competition.
http://www.seakart.com/ This is the local club site. Pretty lame site but will give you some info on the local events etc.
