I was at the Suplex presentation during the Williams open day a months or so back. Listening carefully to the presentation three were a couple of comments about the M3W suspension, one in particular was something about the geometry that made me wonder about the true reasons why they stopped supply.
I spoke to their consultant, name escapes me, and he was carefully not to say very much of substance.
BUT putting 2 and 2 together my conclusion is that Suplex felt the M3W front end to be so flawed that they wanted nothing to do with it. He said they are working with the factory on an upgrade. I wonder if this is the "Comfort option?"
Just my deluded thoughts you understand.
