I'm a new member,so probably moust of you just know what I'm going to indicate but I'm sure that can be usefull for someone;-)
If you ha a smartphone with gps integrated or a gps bluetooth aerial,you can download a very nice program to take time's lap on track(with all world circuits,intertimes,and able to create new tracks)and misure your performances and a lot of other nice things..
RaceChrono - The GPS Lap Timer...
it works!!!!

I'll vouch for it too. Plenty of the fellas use it over here in Oz for their trackdays as lap timing is not allowed on many tracks and Racechrono is perfect as it can be hidden quite easily.
