If you really have a lot of time for the project (starting early in the star's burn?), you might try using photovoltaics to move a lot of mass across the surface to ahead of where tides would accumulate, slowly speeding up the day/night cycle. The faster you spin, the flatter your geoid and you should probably stop accelerating before your entire equator region goes interplanetary.
