The undercarriage bracing seems to be more extensive than on the F8x, but the rear axle of the old car also had bracing extending to the rockers. The front end seems to have some additional bracing, that's for sure. F80's aluminium underbody panel was designed to be structural as well. Otherwise, it's all the same. Nothing new.

Under the bonnet, I cannot believe they've replaced the beautiful CF piece with an ugly steel unit. That piece also no longer extends to the A-pillar. The bulkhead brace made of Al was retained and a steel strut brace between strut towers was added.

Torsional rigidity of the F8x is not far away from the E46 M3 GTR as per Biermann's very educational M4 walkaround from 2014.

And thanks for filming it vertically so I couldn't see as much!
