It looks fairly stout. Not a lot of changes, but buggies haven't really changed in many years. It's evolutionary, not re-inventing the wheel.

I'm curious about something: I haven't driven a pivot-ball car since the B3, and I notice that very few (if any) drivers use optional light-weight pivot-balls. In fact, I've seen a few add weight to the front uprights. Does the handling improvement outweigh the benefit of shedding a few ounces of unsprung weight?

I would error on the side of maximum durability even at the expense of a bit more un-sprung weight. Steel also lasts longer than aluminum, and is more slippery for smoothness.

As for adding weight to the hubs, that will make the car more lazy, effectively slowing corner entry or transition. I could see it as something to try when running on a very smooth surface, but I would rather add weight to the chassis.

Typically you see weight added to hubs on tracks with the highest traction, Asian and Euro tracks. Luke stated above, it slows things down a bit and makes the car easier to drive.

Forgive my ignorance, but wouldn't you be able to accomplish the same steering slowing by dialing in some caster with shims or by adjusting the speed of your steering servo as opposed to a change that incurs a weight penalty?
