John:
I like how your lakester is progressing. It should prove very fast once on the salt.
Driving position looks comfortable but egress may prove difficult when trying to get your feet in a position to push out of the cockpit. Since your legs and feet are substantially elivated, it looks like you will have to do a sit-up while pushing back against the seat thereby clearing your helmet from the roll bar and knees from the steering wheel hoop. Looks like a task for a young, slim, physically fit driver. I am the exact opposite and getting worse with age.
BTW, did you say what engine you will be using?
