The wheels are 16inch.
The arch is just what fitted.
The floor is just the same, I have moved the seat as far back as poss, so you now sit on the floor with your legs streatched out in front of you. I am 5ft 8, feels right to me!! Cant see much though?
lol very tempted to try the same sort of peddal box in mine (MK6 escort) but not sure how itd sit, you putting a false floor over it I guess? to rest your heals?
also liking your choice in fule lines, I want to run black fuel lines and oil lines from dry sump in rubber as not keen on braided stuff.
