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.
