Thanks DayMog that's an interesting suggestion. The crucial issues as I see them are getting in and out (solved with a detachable wheel), the distance between my knee, the dash and the wheel/indicator and what I do with my feet when I'm not changing gear. The cut out well for my heels could be an interesting suggestion. I'm certainly not as tall as you friend and my legs won't be as long so this could definitely free-up an inch or more of additional room with very little fundamental change to the car.I'd like to avoid changing the seats if possible but maybe change foams and density on my side and lower it slightly and with the floor change this may be enough.
All good suggestions...keep 'em coming!
