Ah. Hmm. I'm not sure I've ever seen a locked rear diff and open front diff used for anything besides drifting. Might make a rally car more exciting on pavement, but uncontrollable on dirt. I suppose the remote-locking feature would take care of that, though.
The Axial Yeti comes stock with an open front different and a locked rear.
