I posted this on here a while back and got told off and was told to post it in Racing comments instead and the thread here locked.
This is a combination of info from here and other sites, but primarily myself searching for circuits using a number of well known circuit sites (and personal knowledge).
There are over 900 items in the file now.
I have tried to put the location icon as close as possible to the startline/pits. For race circuits it's easy to see the layout, however for road/street circuits it's not so obvious, as such have a look at the following sites.http://www.racingcircuits.net/http://www.gdecarli.it/.%5Cindex.htmhttp://www.silhouet....cks/tracks.html
The key I've used is
Red Car = old Circuit
Yellow Car = Current circuit
Green Car = future development
With a ring round it it's a test track.
A building is a factory or similar.
If anyone has any corrections or additional circuits then let me know as I'll try and keep the file upto date.
