still surprised to see it was ahead but half a second in what is a pretty short lap.
400 pounds? Maybe for the Coupe with a CF roof. Keep in mind this was a sedan and was most likely equipped with a moonroof.
According to THIS test
C63= 3,957 pounds
M3 3,681 pounds
Difference of 276 pounds. Also many things can influence a track time...we don't know the factors each car was driven in, tire tread, drivers etc.
