I have a 2012 Plus 4 and although I am a mere 6 foot I have very long legs that require the seat to be all the way back. There is a little space behind the base of the seat but with the seat back inclination that I prefer there is probably only half an inch, if anything at all, between the seat back and the vertical front of the cover that encloses the diff and suspension components. Shifting the runners back would not gain me anything with my car.
