Raising the front of the seats will improve the leg room for the driver. Passenger is fine without. I would also use the space under the driver's seat for documents like the owner's manual, registration,and necessary legal papers in a water proof bag as there just isn't much space anywhere else for that stuff!
The seats are fine. The biggest problem is that the swing arm for the rear wheel is just about at the same point as your hips! You hit something and it will be transmitted to your joints and flesh. A few pot holes, frost heaves or whatever will try to rearrange your internal organs! The suspension is hard, read 'normal' for a Morgan.
My tag line for a time was: "I bought a British hand-built barely street legal race car. What was I thinking?"
I was not far off. When your bumm goes numb, it's time to take a break...
