Fit 5 link supension. You get a comfortable ride, panhard rod, and there is no need for anti tramp bars. Handling is improved as well.
You will never get a limousine ride with a Morgan because of the ancient chassis design an the limited travel but a 5 link suspension system will keep everything under control and optomise what you do have. Even Morgan went to a 5 link system on the ARP4.
+1, I can’t comment on any of the “cheaper” options, and if they work for you that’s great, but the 5 link suspension totally transformed my car. So much more positive cornering means less need to slow down, less crashing when you hit a pothole, and much more control during “spirited” starts.
SWMBO says it’s more comfortable which is an added bonus. The only downside as far as I’m concerned is the price.
