Interesting to hear that other Plus Six owners are experiencing the same problem of loss of ride height. At first we thought that the only worry was scrapping the muffler and the engine sump however when we sought a solution we were told (I repeat from another thread);
"One issue with the PlusSix, is that the springs, which are good quality, are made to competition principles.
By that I would consider the designs to be inadequately durable for road car use. Put simply they will collapse in service over time."
This could well be more serious than the present potential brake failure as having the suspension collapse when travelling at speed could be a real disaster!
In New Zealand we use our cars mainly for touring with cases on the luggage carrier (blame our wives for the load!) so we, four Plus Six owners, have decided to fit replacement SSL coil over damper units all round. These units are to have adjustable spring platforms so that should we loose ride height again then they can be adjusted back to give the original factory 135mm front and 155mm rear clearances.
I have contacted my UK dealer who passed our concern on to John Bower at MMC, but have not had a response from him. So we have pushed on and order replacement kits from SSL and they should be shipped in a couple of weeks.
It would be interesting to know as to how many Plus Sixes are affected by this problem and what their owners have done.
