That's probably a common misconception, but you don't sit ON the aft spar, your butt ends up down the front side of it, with the "small" of your back up against the aft spar. If you tried to sit ON the aft spar, the canopy would have to go up about 5 inches higher than the drawings show. The stock sling seat is hung over the front of the aft spar, and that's where you sit. If he's only 5'-8", that'll probably work out OK, but the next guy may not think so, if he ever sells it. In my plane (and other KRs), it's the bottom of the fuselage just in front of the aft spar that defines the maximum lowest point of the seat. I'm about 6', and I'll have just enough room for headphones and an inch of clearance with my canopy 17.25" above the longeron, with my seat bottom touching the floor.
