Glen, with the above setting, ground clearance is 3.5 in. at the
oil pan. That is the lowest point on my car. That is with a stock style steel pan. The next lowest point is 3.75 in. at the mufflers which are under car mounted. The frame is at 4.25 in. front, 4.75 in. rear. The frame would be the low points if running low profile pan and side exhaust. There is probably 2-3 in. of suspension height adjustment.
