According to the same data sheet: - the tested M2 Competition (M-DCT) weighed 1631 kg (full tank of fuel included), apparently had no M Driver's Package (because data sheet notes V-max of 250 km/u (stock: electronically limited V-max) - Parabolika speed 232 km/h), featured steel brakes, was sitting on Pilot Super Sport tires (likely on 19" 788M wheels) and was driving in 1°C/34°F air temp + 1°C/34°F track temp and 1020 mbar air pressure;
- the tested M2 CS (M-DCT) weighed 1588 kg (full tank of fuel included), apparently had M Driver's Package (because data sheet notes V-max of 280 km/h (delimited V-max) - Parabolika speed 248 km/h), featured M-CCB (carbon ceramic brakes - bigger rotors), was sitting on Cup 2 tires (likely on lightweight 19" 763M wheels) and was driving in 32°C/90°F air temp + 53°C/127°F track temp and 1015 mbar air pressure.
Hm, judging merely by those figures, it looks like the M2 Competition - considering its setup and near freezing point test circumstances - wasn't particularly blown out of the water/ice by the better equipped and more powerful M2 CS pushed around the track in warm weather on hot asphalt.

So to "even out" the comparison they fitted the M2C w/the same brakes otherwise they are comparing stock M2C to stock M2CS, which probably accounts for the tire difference.
So what I learned/confirmed from this is that comparing cars based on spec sheets is only relevant for bragging rights (40 HP more, 100 LBS less) vs. real world performance.

Since the M2CS appears to be an M2C + M Performance car.
For example, the M2CS has the 768M but w/the Michelin Pilot Sport Cup 2 tires, which is the only 768M package the dealer can order. Yes, we went back and forth w/BMW on my M2C order and I could've gotten the 768M wheels only instead of the 788M but it was a special request not a check box on the system and there was no credit for the 788M wheels.
So I wonder if by using the 2NH red calipers if the M2CS is also fitted w/the track pads that are included in the retrofit kit instead of the street pads?
