Very interesting. Note also that Porsche was a fan of swing axle rear suspension, and I think, the 8C 2900B uses that concept.
Yes, that is correct. The transaxle is attached to the frame and doesn't move (remember, the drive shaft turns at engine RPM). The swing axles are supported by a transverse leaf spring and dual-jointed trailing arms (on the outside of the frame rails) that also dynamically adjust the toe-in of the rear wheels throughout the suspension travel range.
The front suspension and steering are pretty sophisticated, too.
These cars are interesting and beautiful when you see them at events -- but absolutely stunning when one can study them from underneath on a hoist.
