Double anti-roll bar

I’ve read about Geoff’s thicker ARB and heard of these fabled thicker ARBs on early cars.
Has anybody ever installed another ARB to reduce roll without fitting stiffer springs ?
Guess you’d need some kind of block bolted to the subframe, which splits in half to allow ARB installation. A similar block at the strut end too.
Is this idea bonkers ?
Does remind me of the double calliper trick, which used to be quite popular.

In theory it would work, if an anti-roll bar can be modeled like a spring, adding springs in parallel gives you a single spring with the same sprint constant as the spring constant of the two springs added together.
Figuring out the mountings and the geometry is another matter.

I had a double anti roll bar fitted to an Escort Mexico that I owned in the seventies and tried to copy the idea on the Sprint but gave up and made a thicker standard type one from a Sierra bar (what else). At castle Combe it made no difference to lap times but did not crash potholes so much. What happened to it I cannot recall because I junked it as a waste of effort.
Good luck Richard.
