Will this lip lower my ground clearance?

This lip extends downward from the bumper, so yes — it reduces ground clearance slightly. Measure the lowest point of your current bumper and compare it to your approach angle before final fitment. You may need to adjust your driving route if you frequent steep driveways or unpaved terrain.

Does the FRP material flex, or is it rigid?

FRP is a hard panel material with moderate flex — it can absorb light impacts without cracking, but it's not designed to bend repeatedly. Avoid curb rash and heavy contact; if damaged, it can be repaired with epoxy or fiberglass patch kits, or replaced as a single unit.

What mounting hardware do I need?

The lip ships without fasteners. You'll use your vehicle's existing fascia mounting points or drill new holes to match the lip's bolt pattern. Stainless steel bolts and washers (typically M6 or M8) work well for this application — reference your vehicle's service manual or fascia design to confirm the right size for your setup.
