Will this affect my ground clearance?

The performance lip extends downward from the existing bumper line. Before installation, measure the lowest point of your current fascia and compare it to driveways, speed bumps, and parking lot approaches you encounter regularly. The extension is modest, but final ground clearance depends on your suspension setup and driving style.

Does this material flex, or is it rigid?

FRP construction delivers a hard, rigid panel. It will not bend under light contact, but unlike urethane, it has minimal give. Inspect for cracks if struck; minor surface scuffs can be sanded and refinished. The material handles UV exposure well once sealed with paint.

What fasteners or hardware do I need to secure this?

The lip is engineered to use factory mounting locations on your M-Sport bumper. Verify your vehicle's bumper bolt pattern and hole count before ordering, then source fasteners rated for plastic-to-plastic or plastic-to-metal attachment. Your vehicle service manual will confirm the correct hardware specification for your setup.
