Installed the comfort kit on my '13 and what a change! From the beginning I was not one who complained about the bump steer and had just accepted it as part of the character of the 3W.
I bought the kit 2 months ago and it sat in my shop since. Got tired of seeing it on the work bench so I took some time and installed it.
Quite an easy process as long as you have a 46mm deep socket and an impact gun. First side took me 30 min, other side under 20. I aligned the tires for zero toe.
Now it drives like a modern car. Steering is light, turn in is smooth and consistent and you don't have to adjust steering angle mid turn.
I can't see spending any extra money for the front suspension arms or other kits available.
It would have been nice if Morgan would have provided the kit to owners free of charge due to their design flaw, but at 150$ it wasn't too painful.
