Yep no standard fitment. The options seem to be what you've suggested....
1. buy a kit and take apart and work out how to fit
2. retro fit all the original gear from a car with front and rear factory diffs. Find out a way to manually activate it, as not easy to retro fit the electrics too.
I prefer option 2, although its clearly loads more expensive. Due to cost, this one is on the back burner....
If I had my time again, I'd buy a car with these options on, too far in and too expensive to swap now.

Okay, I guess I'm maybe just stupid but… Why do you really need a rear locker on these cars? Doesn't the traction control automatically send power to the wheels with traction?

I asked Quaife about this years ago, believe they said get 10 preorders and they'll make them...

That's actually a great question. The "problem" with ABD (automatic brake differential) which uses braking intervention to stop a slipping wheel versus a locked differential, is that momentum is lost as well as more even drive force distribution to the ground. This increases the risk of getting stuck since enough force may not be able to be applied to the reduced number of wheels with traction to keep the vehicle moving.

There are also stability benefits when going down loose surfaces with a locked rear and center differential; similar to the effects of LSD's on race cars under braking.
