steep downhill coasting

There's a long downhill that I do periodically, with 4 miles of it approaching 7 percent grade, including two sweeping 180 degree downhill curves. Before any mods I did all of the downhill in 5th gear. This transitioned to 4th gear after grill blocks and wheel covers, which may or may not have included some touching of the brakes.

The last trip with the new bumper cover the car was flying down at high revs in 3rd gear (approaching 55-60), and lightly touching the brakes didn't seem to do any good, which freaked me out a bit. Is it possible the car could rev too high in 3rd gear? What if the car is still going too fast, just ride it out, use the brakes more, or start out in 2nd at the crest?
