I'm a daily driver and I get up to 70-75 mph a few times a week. My Fulton sunvisor has been screwed on for 8 years, hasn't moved yet. My visor has 8 screws, thats 4 per side, and the two center bar clamps.

"...my good horse Rocinante, mine eternal and inseparable companion in all my journeys and courses." ...Don Quixote, Cervantes
"If you come to a fork in the road, take it."...Yogi Berra
"Rudeness is the weak man's imitation of strength." ...Eric Hoffer
