That’s why I’m confused...i marked it in the second session of the day, but then turned head unit off for 3rd while instructor was onboard, then turned back on and recorded the 4th session. If you guys can see these pics, there is the line i marked in the first one, and the actual track finish line in the second...but i didn’t mark that one and it didn’t split my laps up.

Sorry for the terrible pics

OK, thanks.

I’m going to continue giving this some thought.

How much downforce do you think you would need to keep the rear end from rising? 100#’s? 200? More?
