front hydragas pressure

[Stuart]

Yes there's an inner membrane between the gas and the fluid.

That's the rubbish bit of the hydragas units. In the end mine was pumped up properly with liquid so the car had the proper height at the front wheels, but the springing action was completely gone. It's the only way to adjust them, but what these units would need is a way to put nitrogen in the head. Or better get rid of them. I just bought a brand new OEM front subframe for modification to accept the Watson springs. Can't wait to have it on the car.

Would it be possible to completely empty the units, then drill a hole in the top and fit a Schrader-type** valve, then have it filled with nitrogen?


** Sorry, don't know how to do umlauts.

I believe that was a common tuning trick on the MG Metro Cup race cars.
