Went into the office today for the first time since last March, and in the way in, found myself in traffic next to a parked FK8, and it dawned on me that they're very similar size wise to a Civic M.
Just been checking out of interest, and these are the dimensions for the wheel track and wheel base.
FK8 :
Front/rear track 1,600/1,593mm
Wheelbase 2,700 mm
Mc2:
Front/rear track 1,465/1,470mm
Wheelbase 2,620 mm
Now that would be a cool (and expensive) swap...with some flared arches of course.
