So today I went to Williams for fitting of the new 6 pot callipers and vented 300mm discs. There were some minor issues which are being resolved tomorrow, but they fitted all OK, I will report on the brakes next week once I have used them in another post next week.
The end result was that I have been loaned the Williams Morgan with 5 link rear suspension and had a 90 mile drive home in variety of conditions. Various people have asked me if I have driven a Morgan with 5 link and what I think, so here it is.
The return journey was down the M4/M5 for 60 miles (a mistake as I spent 30 minutes in heavy traffic due to an accident

), and 30 miles on twisty A roads.
1. Rear end feels more stable, I believe due to less rear body roll
2. Turn in and stability is good, as a result
So is it better? Well this will depends upon what you are looking for IMHO, I have had a few opportunities to push hard through bends and there is no perceptible over or understeer. But if you are looking for, or expect, a more comfortable and easier ride then you may be disappointed. In fact I think it is much the same in ride comfort as a trad setup with pan hard rod, although maybe it is how it is setup on this car. I did hit a few big bumps and to be honest I did not think much difference to how my roadster reacts. The one area that is an improvement is cornering predictability, and I suspect once you feel confident could push on pretty hard. Much as how I experienced in Peter Ballards car as a passenger.
Is it worth the cost, a very difficult question to answer, depends on how deep your pockets are and what you want from your Morgan. IMO there are quite a lot of owners out there who like to think they are raging boy racers but aren't really

, maybe I am one of them. If you are then you will probably like how it feels and improves cornering. If you are a more tame driver then maybe its not for you.
I would advise anyone considering it drives a car with the 5 link for a sensible amount of miles first and makes up their own mind.
I will be returning to William on Monday morning and will take the pretty route with down some varied A roads with some nice twisty bits, so will try and push a bit harder and report further.
