I made a set a couple of years ago in readiness for jobs not yet done & one reason for this is the dearth of information on the advantages of having them fitted.
Is it to compensate for a sagging sphere or is it a “track day” mod’?
The beauty of hydro gas is the interlinked suspension, what goes up, comes down, to compensate & it’s this that provides the unique properties of this system in a sports car.
Taking this to its logical conclusion ; remove all the interlinked pipe work & fill each sphere individually via a shrader valve fitted locally.
This need not involve having a valve on the unit, it can be achieved by using a further two
RNP100180 pipes, complete with the Schader valve (off a scrapper).
These would be fitted with an end blank & applied to the rear & the front network, as normal but again with blanks to localise the fluid to the front spheres.
I’ll leave this here for now, but when I have the car out after & I can safely lift the boxes down I’ll take some photographs to illustrate.
