On tracks with good surfaces and mild curbs, live rear axles are fine.
It's when the track is bumpy as fuck where axles struggle.
Every road imperfection that hits one side also affects the other unlike IRS.
Axles have advantage of being mostly parallel to a surface at all times.
They also have a little bit of rear steering built into the geometry.
& Have vastly superior anti squat characteristics.
You can also have Cambered solid axles as well But require routine maintenance.

Basically, solid axles arn't nearly as bad as people think.
