Using stock 4kq front sway bar as a rear bar

[Brian Devlin]

Maybe you could just put really soft bushings on there to reduce the
effective stiffness. Or attach the bar to control arms inboard of the
normal location? I'm sure there are many ways to modify the
stiffness. Just don't weld the bar to the frame; I'm pretty sure
that's a bad idea.

Here's another thing to think about: some off roaders use a bar
that's split in the middle and uses a sleeve to connect/disconnect
the two halves. If you could rig that up, and control it with a
vacuum servo (tied into the diff locks?) then you could soften up the
rear when you need extra traction. Wait...don't do that...I have to
patent it first.
