Hum, my english is quite rusty but I will try
Is it quite notorious that an all-plastic car often leads to more mechanical grip. You have less weight, less stiffness, more give, and your car becomes easier and faster than a all-metal aluminium basher car.
I think that the new hubs allow the car to have a little give, so you get a little more grip, maybe also less breakage of the wheel axles. And as you said, you also get the benefit of less wear and less unsprung weight. Win-win in my book
Wow I did it
