The pad doesn't extend to the outer edge of the rotor, so doesn't wear that part. The depth of the lip is how much thinner than original your rotors are. Measure them. If they haven't gone below the minimum thickness, the only problem with the lip is if it causes noise. You mention the driver's side. If they vary side to side then something isn't right, maybe a sticking caliper on that side.
