The leader boards for each car on each track in both series are now posted online:
The only catch is that these boards will be wiped clean when a physics update changes the way that cars handle, with the next update coming either July 19 or 26 most likely. Right now, the leader boards are a mix of old and new physics from the last two updates. Since updating to this week's release (with manual shifting) most of us can't get any where near our lap times from the week before due to the cars being heavier and a bit slower. The devs are working hard to get the physics of the cars as accurate as possible and with each change comes the reset of leader boards to make the competition fair. They have stated that within the next month or two, these changes SHOULD be mostly done so then things will stabilize for a while.
