As Lightspeed says the oil cooler and lights don't sit any lower than the license plate panel. I have the same oil cooler and do have to be aware of the ruts and holes on the mountain tracks I have to drive on but that would also apply if I didn't have the oil cooler and just the standard set up.
Must be an optical illusion - looks to me too like the RH lamp (as you look at the photo) is a mere cm or 2 above the tarmac!
