Will this air dam create interference with speed bumps or steep driveways?

The lip extends modestly from the factory fascia line. Verify ground clearance on your typical routes before final installation—inspect how low the front bumper sits and whether additional splitter support is needed at your preferred ride height.

Should I drill through the bumper or use adhesive to secure this?

This lip is designed to work with factory mounting points on the front fascia. Adhesive-only installation is possible on smooth surfaces; drilling through the OEM bumper skin offers the most stable, long-term hold. Assess your bumper's construction and choose the method that suits your install confidence.

What prep work does the FRP need before painting?

Sand and prep the surface thoroughly before applying your chosen primer and topcoat. FRP shipping in raw FRP condition means it's free of mold release agent residue, but surface roughness from the mold will need sanding for a smooth, durable paint finish.
