I take it the coil overs aren't adjustable for ride height?
It looks a little high compared to the "in the weeds" look that many rods sport. I'd say you can go a little lower w/o sacrificing ride quality, but it's a fine line. But I would be concerned the ride every bit as much as the looks, if you plan on actually driving it.
Without going to bags or hydraulics, there has to be a compromise. Using springs, you can go low- but it's going to be STIFF or it'll bottom out. Neither of which I care for at all.
I'd see what it looked like fully loaded (sand bags work for a mock up) before changing anything.
