That does not mean the B58 engine is 59kg heavier, it means there's 59kg more on the front axle. As we agreed the brakes and alloys are heavier, and the engine is longer which means it's putting a larger proportion of its weight on the front axle. So that 59kg difference on the front axle is coming from a combination of factors, not sheer engine weight.
Once again, to clarify: I'm not saying the M40i doesn't have 59kg more on the front axle. It clearly does as evidenced by the documentation you provided.
I'm saying that it's impossible for the engine to be 59kg heavier. Big distinction there.

Both cars in AMS had adaptive suspension and sport brakes
60 kg is nearly the truth of engine with aggregates and in-/outtake and OPF.
