Does the F80 change any major parts of the unibody from steel to aluminum, like the front clip?

The official threads have discussed the differences between a F3x and F8x chassis. Do you really believe they would weaken the chassis on their M model?
None of the lightweight components weaken the chassis, instead the CFRP strut brace increase stiffness as well as do the solidly mounted rear subframe.
