Ohh broken wheels thats sad and expensive.The roads here (Scottish Borders) are unusually rough. If you go too firm you get punctures and broke wheels.
I'm not sure where you are, but id hazard the roads are better than they are here. Us British seem uniquely incapable of building decent roads. And then maintaining them.
Where i live I'm surrounded by forest, and articulated trucks pound the roads all day.
A setup that works fine anywhere else...well, in europe..will just be giving punctures, broken wheels...shock absorbers...ball joints...suspension arms..☹
Maybe a rallye suspension is better solution at bad roads, i would look at öhlins rallye
