At the resto show I talked with Julian Crossley and Richard Gane about the modification made to Julian's Javelin that gives it impressive race track road holding.
The rotation point is moved from beside the left torsion bar to behind the left shock absorber lower bolt. This is done by constructing an A frame. The rod is horizontal with the other end attached at the right lower shock absorber mounting.
The solution was verified using computer design tools fed with all the relevant Javelin data.
Whilst impressive on track I do not know how it would perform in rallying conditions with much more suspension travel.

Re: Panhard rod
I would assume that you would want the axle to, in effect, move straight up and down with no sideways movement.
For a given body roll, a longer Panhard rod (that this appears to be relative to the standard rod) would describe a larger radius about its fixed point on the chassis resulting in less sideways displacement of the axle. Better still would be a Watt linkage which would require a central pivot point bolted to the diff casing.
