How common was the dry front end and hydro rear? Does it effect performance and if so does it increase or lower it? What are the advantages if any? Last but not least what model's would you find this setup on and was it factory fitted?
My 2 cents:
AFAIK Hydrolastic is a sealed unit with dampened displacement front to rear and vice versa. One sealed system either side. Just like other fluid systems - there are no moving mechanical parts to wear out.
Having the rear blocked off from the front may still give you some movement via the compression of the low preasurised sealed fluid line and diaphram unit, but I would seriously suspect that it would be a rotten road holding alternative to simply replacing/reconnecting the proper hydrolastic system.
Even if changing from 'wet' to 'dry' (as lots of owners seem inclined to want to do) is to get better 'performance' from a mini, hydraulic systems have been used in big money engineered competition cars for decades with great success (sorry the Citroen owner comes out in me now).
Sounds like yet another butchered car to me.
Be brave and give it back what it was intended to have. If you really dont like the hydro - then it seems an easy weekends work and a few rubber blocks to the change it to static suspension.
Q: Are there really that many cases of unreliable hyrolastic systems in BMC products:?:
