Will this interfere with my trunk seal or undercarriage at speed?

The front lip extends below the bumper line and is designed to work with factory mounting points. Verify ground clearance on your specific setup before installation, especially if you run lowered suspension or have modified ride height.

How do I maintain the carbon fiber finish?

Wash with mild soap and water, then dry with a soft cloth. The clear coat protects the weave from UV and oxidation. Avoid harsh chemicals or abrasive pads. If the clear coat scratches, light sanding and recoating will restore protection — prep the surface and apply your chosen automotive clear coat per the manufacturer's instructions.
