Do these mount to factory attachment points or do I need to drill?

These are designed for factory mounting points on the door frames — no drilling required. Test-fit before final installation to confirm fitment with your doors.

Will these affect my visibility or obstruct my view?

Smoke tint reduces glare without blocking your sightlines. You'll still see clearly through the glass; the tint just cuts brightness and reflection from direct sun.

What do I need to prep before installation?

Clean the mounting area on your door frame with soap and water, then dry completely. If adhesive is part of your mounting method, let surfaces cure per the fastener manufacturer's instructions before closing doors.
