Will this lip hit the ground at a shallow approach angle?

The HM-S profile sits close to the bumper line without radical extension. Ground clearance depends on your suspension setup and driveway slopes. Inspect the mounting brackets before and after installation to confirm the lip sits at or slightly below the OEM bumper edge—typical for stock ride height.

Is this rigid or does it flex during daily driving?

FRP is a rigid panel once bonded to the bumper. It won't flex or rattle under normal road conditions. The material is strong enough to handle minor contact without cracking, though impact at speed can cause damage—treat it with the same care as your bumper cover.

What prep does the Raw FRP finish require?

Sand and prep the surface with appropriate grit before applying your chosen primer and paint. FRP absorbs paint well when the surface is clean and slightly scuffed. Follow your paint brand's instructions for adhesion and cure time.
