The rockers have been dropped 2" to hide the pinch but at ride height I have about 4" to the oil pan and 6" to the bottom of the rockers. I have never had a problem with clearance at proper ride height.
I have a popsicle stick worth of clearance to the oil pan when it's dropped all the way and it's about 2-3" to the bottom of the rockers.
RMS front suspension using ride tech - air ride.
Here's a pic of it at ride height.
