Ideal for the axles would be straight out, yes. Less CV wear. But it wouldn't be ideal for the control arms, as you'd be rocking them past the neutral point. Optimally, they point downwards and never come above flat. Anyone with a 3" drop has their car too low for optimal suspension geometry. You'd need to raise the subframes in order to be that low properly.
