Dean G.,
No, you haven't been missing anything. These fenders (originally designed for the WCM Ultralite) are flush at the bottom of my car (forward of the tire) and truly do hang down below the rear quarter; larger, longer fender. All things considered, this was the best fitment I could come up with that served the purposes of both form and function. I’ll post a few more pics (side view) which shows the flush portion forward of the tire along with the overhang in the rear. Future plans call for adding a rear difusser to 'tie' it all together.
