@silente, what numbers do you have for Perrin's open source LMP1?
I have around 9066N of downforce at 240kmh, and 2000N of drag for the same speed.(no specific ride height but with a LM low drag config)
Very low figures when compared to Dome's(2011)12300N of downforce(240kmh), 3000N of drag , also on LM setup:

The variation of aero figures for these LMPs is quite considerable, though. Here are values for a "generic closed top LMP2":

silente, do you have values for Perrins's F1 open source?
