Anti roll bar

[snapper]

An anti roll bar helps the handling by allowing softer damper and spring rates while indeed reducing roll. Roll bars can be adjustable by varying where you attach the uplinks relative to the wishbones and the forward or rear link bars i.e the bits of the roll bar that point back or forward relative to the part that runs across the car.
On my (not a haynes) car the sierra anti roll bar forms part of the lower wishbone with the standard track control arm, in this configuration it is indeed to stiff, even the thinnest of fords anti roll bars is to thick.
So i milled the bar across half of its width to half thickness and it works well.
Using standard steel rod will probably not work as it is not sprung and would just twist and settle over time.
