I have this lip and think it looks fantastic.
However I have rebuilt it 7 times over a 16 month period. I have 4" of ground clearance at the front, center of the lip.
iND kindly offered to remove it for me when the M3 goes to them shortly and I declined. It's that good looking (in my opinion).
Slanted driveways are a problem unless you can angle your approach/ descent.
