At the OEM level of detail, I think you'll find that Stielow et al have really "sweat the small stuff"...

If that were to be correct, than 160 + 140 lighter motor would account for the TOTAL 300lb curb weight difference. Given they've reduced weight of other components (rear seat for example was 40+ lbs alone plus thinner rear window, lighter seats, no fog lamps, etc) this leaves me confused as to what you're suggesting.

The sprung AND unsprung weight differential, Base-to-Base per corner, approaches 40 lb. Wheels-tires-suspension-brakes.
Edited, and thanks.
