I had this same concern.
With stock height I had no problems with speed bumps. I did have to slow down when approaching a steep driveway, but overall no clearance issues.
I did have to back into a lot of parking spaces, as it will hit the parking curb block.
Just in case you consider lowering in the future..
I just lowered on H&R's and I have had no problems with speed bumps so far. I do have to angle into steep driveways though. But overall with some care, the lip will be fine.
