Haha, its so quiet! it's the silent killer!!!

Nah, that's not me. It's a nice conversion though. He's using a motor coupled to a Suzuki Swift gearbox, which I think requires some modification to the subframe. I'm trying to avoid that this time and would rather use a slightly bigger motor (or two) with a single reduction. Unless you're aiming for a high top speed there's no real need for a gearbox.

This is what I'm working on now. I've got a bit of runout in the stub shafts that carry the pot joints, which I need to sort out before I install this.

Are you not running a differential on that Malcolm, I would have thought you'd get a serious amount of under steer with that kind of set-up.

Tupers: The wheels are driven independently by the motors, like Ethel suggested. There's no physical connection between them, but the electronic controller acts like an open diff. When one motor slows down the other speeds up automatically. I'm just looking for an alternative solution for my next project that will involve less fabrication and place the motors even lower in the subframe, to make more room for batteries.

Wil_h: Thanks for the suggestions. The MX5 diff looks interesting as I might be able to use the cross-member that it's bolted to to mount the diff straight across subframe.

I've been checking out all your suggestions and it looks like the winner is the Freelander diff. Thanks ANON! It's nice and compact, weighs about 7 kg less than the nearest contender and is fairly easy to get hold of. The only drawback is that it's also in demand, so prices aren't cheap. Never mind, three out of four ain't bad.

Thanks for all the help!
