“I never believed in the unsprung weight is bad theory in the first place.”
It does have some affect as does the additional rotating mass.
Ford has shown that with the GT350R.
Rotating mass is a separate issue, and depends on the moment of inertia. Which is less of an issue with electric hub motors, vs stupidly huge and heavy wheels and tires.
The discussion was about unsprung mass and ride.
When Jaguar moved the inboard brakes to the rear wheels for the XJ40, they were surprised that the ride improved.
For me, larger mass with same spring rates gives lower resonant frequency and absorbs a greater range of higher frequency vibrations.
