The only reason for a shake is that a wheel or hub assembly is not running true. If a tyre is out of shape, balancing will not fix the issue
take a look at the last 10 minutes of this vid
https://www.youtube.com/watch?v=4cx9apL7HhYIf your hub adapter is not faced correctly, this will also introduce a shake, if your adapter is not flat against the hub, this will introduce a shake/vibration. if your discs are not true to the hub this will introduce a shake vibration
Basically what I'm saying is that, it's a process of elimination. You know the wheels are balanced, but are the tyres sitting on the rim correctly?
I would then look at the hub area, bolt the adapter up securely then trace the edge with a dial Vernier, this should tell you if the mounting face of the wheel is flat and true.
Unfortunately the extra stuff bolted onto the drive train increases the chance of some vibration, which means tracking down the fault becomes more of a chore.
Hopefully some of the 430 owners may be able to shed some sort of light on this issue, my set up is not DNA or Toyota
