I'm toying with the idea of doing a full Roadster upgrade next winter, because I'm very much attracted to the big engineering jobs, and there are not many left to do. My Plus 4 is fine as it is, and although my Roadster is very enjoyable, and I never get complaints, the five link rear end is a job worth tackling in terms of satisfaction.
I've only had my Roadster with SSL 5 Link for a short while but the back end feels much more under control and less harsh on bumpy roads.
However, be careful as there are people who claim that cars with the 5 Link Conversion are no longer real Morgans as they don't have leaf springs.
