Citroen ax suspension info
Discussion
If you don't know, I am entering the mongol rally this year in a citroen ax (more info www.lostandhungry.co.uk).
The generous people at Eibach have offered to give us some suspension springs but we need to supply them with some info that we don't have.
We need to know:
Spring rates,
Damper rates,
and damper settings
We are going to be travelling over mountains and desserts so need pretty generous ground clearance.
Anyone have any ideas where we could find out this sort of information???
Or even better anybody know this information?

Depends really whether you plan to be attacking the stages for ultimate speed, or would like a car that rides more comfortably.
If you were to use a rally car set up for gravel as an example, the suspension is set up far harder than you would have on a road car as you want to be able to tackle the large bumps and dips at speed without the belly of the car hitting the ground (too hard at least).
In contrast, a 4x4 off roader has relatively soft suspension to enable the passengers to have a comfortable ride and for the wheels to articulate over terrain.
Having seen the event on TV, I would suggest going for a stiffer set up that raised the ride height, yet allowed enough travel over extreme surfaces. The AX is a relatively popular rally car, and I would estimate that you would want a spring that was approximately 20% - 50% stiffer than standard, and about an inch longer.
Spring rates are measured in lb/in, i.e how many pounds to compress by an inch. Should be easy enough to rig up an apparatus to compress the spring by a distance and work this out. Think in the way of McGuyver!!
Dampers should be "matched" to the springs, but for your event you could probably save a lot of money by simply fitting replacement standard dampers, These would be better than whatever aging ones you have, and would enable you to get replacements quickly and easily.
Not sure what could be done with the torsion bar other than to swap it for a GT/GTi version if yours is a base model.
