While Dan and Peter at SSL initially said that they did not think that the Plus Four suspension could be improved, my guess is that now that the cars have been on the road for a period faults are starting to emerge.
They went out of their ways to produce coil over damper units with adjustable spring platforms for our Plus Six Morgans - nothing was too much trouble! Now we have cars with great handling qualities. So get in touch with them directly at SSL. Kerry
