Have you thought maybe a testing conditions were different? Eg. more in favour of Z4 M Roadster?
The only credible results would be all cars in comparison tested on a same day - in 100% same conditions (same air temperature, same track temperature, same humidity, same weather, same driver, comparable tires, similar milage, similar equippment, etc).
Otherwise all the data are worthless - and can hardly be used for correct comparison.
Btw, M Coupe has the edge over M Roadster.
