I have Suplex front and rear. I must echo the words of those who have given it the "seal of approval". It is oriented towards giving a comfortable ride without detracting from the sporty feel of the car. It is an expensive option but, in my opinion, the best for the touring comfort vs sport ride and handling. It is always going to be a compromise but this will improve the handling as against the standard Morgan setup. If you want a happy wife and still enjoy driving your 4/4 go for it.
We have now down about 35,000 km with the front Suplex fitted and about 10,000 with the rear kit fitted.
For those that prefer a more hard edged approach there are lots of other options, some of which will cost a lot less. These also include fitting harder springs to the Suplex kit and adjustable dampers front and back.
You don't mention what year model your car is or where you are situated. There are quite a few people who would happily take you for a run in their car, myself included, so that you can experience what it is like for yourself.
