Hydrolastic/Hydrogas Suspension
Anyone on here have any experience or knowledge of using the Hydrolastic units from the Metro on another vehicles suspension?
I want to use them instead of steel springs.
They offer greater versatility in adjustment range than a stel spring does. Just pump them up to increase ground clearance, or release some to lower
without adjusting spring rate.
Arguements for and against please?
But no anti Austin or Rover just cuz you don't like em!

For example in the MGF, rover used TWO front metro sub frames, one empty and at the front, one full & back to front at the rear. Hyrdolastic has a lot
to offer, but you need to build the vehicle to specific weights to make them work because the displacer units only come as specific units.
(ie specific spring weights)

JGG,
Does the MGF use dampers on front sub frame?
Are the units linked front to rear as in the Metro?

metro fronts were independant and rears were conected side to side so i supose they are all indipendant,as jgg says they might not be the right
"spring rate" and are non adjustable unless you move the mounting point along the lower arm?
who cares who wins

i have had several cars that have had hydro on it.
in most respects they were a bit hard in the ride.
a hydro unit has gas one side, and fluid the other. the gas, which ISNT adjustable, is the springy bit. the fluid is used to set ride height. the
fluid is pumped in to set ride height and as a bodge when the gas is leaking to try and get the ride height back. fluid cannot compress. so, if you
pump more water in you just change ride height. so, as adjustable units, they dont!
some have a damping action in em - metros from about f reg on dont have dampers - just hydro units. Earlier ones like my c reg turbo had displacers
AND an external damper.
I wouldnt use em.

Early metro's this is true, but later metro's were split left Front & Rear (one connector at rear) and right front and rear (another connector at
rear).
MGF's I think are split like the early metro's but for some reason they just don't seem to go down like the metro's. I've NEVER had a reason to
pump one up. Oh and the front suuspension is metro uprights with a CV joint as the spindle but no shaft, cage or bearings in it. They do look a bit
funny, but they obviously work.
Enjoy.
