Will this lip scrape on driveways or speed bumps?

The lip extends slightly below the stock bumper line. Check your typical approach angles and driveway geometry before install — if you regularly bottom out on shallow slopes, factor in the additional drop. Measure ground clearance with the panel test-fit to the bumper before final fastening.

Is the FRP rigid or does it flex during driving?

FRP is a rigid, hard panel construction. Unlike urethane-based lips that absorb road impact, this material maintains its shape under normal highway use. It will not sag or deform over time, but impacts at low speeds can cause cracking — use caution near curbs and parking lot obstacles.

What fasteners do I need to bolt this to the bumper?

Hardware is not included with the panel. You'll need to source bolts, washers, and any backing plates that match your factory mounting hole size and spacing. Reference your vehicle's service manual or OEM bumper diagram to determine the correct fastener specifications.
