Increasing Front Damping on Xantias
There is an easy method to restrict the jet in the spheres on front strut suspensions such as Xantias so as to increase the damping. I described this to a post the other day, but I have found the modified springs I used, so here is a photo. The size of the spring needs to hold in place when the sphere is fitted.
Surely the 'leg' of the spring will totally block the sphere jet preventing
any/or meaningful amounts of fluid to access the gas beyond in the pocket
of nitrogen in the sphere so it'd be a bit like driving with a flat sphere.
What purpose does the spring end have as it can't brace against the ram's
piston either? TBH, it looks a bit dangerous to fit on a car if you don't mind
me saying so although I'm prepared to listen to an explanation of what's
happening here!?

Nothing moves you like a Citroën
The scheme only works on front struts where the sphere lies approximately horizontal. The pocket on the strut top then provides the brace for the spring.
The leg of the spring does not block the jet, only shadows it slightly. The wire size must be considerably less than the jet size, and chosen according to how much restriction you want. As an example, if the wire is half the jet diameter, the residual area will still be 75% of the original area. Incidentally, early height correctors used this method to calibrate the delay provided by the diaphrams.
This is only a suggestion for those that want to dabble. It does indeed only affect the slow bypass. Most people will prefer the original damping.

Crazy idea to have anything floating around in the suspension cylinder which could damage the bore. If you want to restrict damping either a careful bit of welding (not advised) or different sphere.
