I saw the parts of the kit "comfort" but of which consists the kit "empire"?
Is it the Morgan factory which sells it?
Two points:
1) Although I have not driven a 3 Wheeler with the Empire kit, I am convinced that it brings a major improvement to the handling. Bill Chaplin is an expert.
2) It is not a factory option. I think it should be and perhaps it will be at some point, but you should check this carefully, bearing in mind the legal/insurance implications before fitting it and using it in France.
