here is an interesting question:
dnano body compatibility is far more complicated than that of it's big brother the mini-z. at 1:28, all we have to do is match a wheel offset with chassis built track width and body tolerances for potential trackwidth. for 1:43, we find ourselves dealing with setting kits and all the intricate tiny peices inorder to change a body and or wheels.
would you not prefer to have wheels offered by measured offset alone or in kits that would include/require the setting kits?
it would require tabulating the chassis built trackwidth for each setting kit in order to determine what wheel offset would be needed but this would seemingly eliminate the need for altering the setting kit unless your tweaking minute details.
recently there has been new developments/products specifically to alter then chassis built track width for the mini-z so there are plenty of people that have subtle differences or preferences in these areas and the dnano has this capability built in to some degree.
