Raise ride height

[richieski]

Hi all, been travelling for a while, I'm off to the alps for another season. I would love too gain more ride height. An inch or so would be great for snow clearance. 
I have used it for 2 seasons so far in the alps and these cars handle great with winter tyres. So much so that i can plough through some deep drifts.
Any ideas? i see someone has raised by 8mm using mad springs in the rear for towing.
Are there coil spacers available?

I see there is an xtr+ that has 30mm Lift. Does anyone know the different components? Also does it mean these components can be purchased from Citroën

There is a company in France that adapts vehicles for heavy duty use, sump guards, mud and snow tyres, LSD's, raised suspension and hydraulic 4x4 are all thing they do.

Will try and find the name

I read that Dangel do 4x4 conversions on Berlingos for Norwegian postal service and possibly others. There are Youtube videos of them,
