Will this interfere with my trunk or undercarriage at speed?

The AP-style design sits below the front bumper line and does not extend significantly into wheel-well territory. Check your vehicle's existing bumper-to-ground clearance before installation to confirm compatibility with your suspension setup or any lowering components.

Should I use adhesive or drill mounting holes?

FRP front lips are best secured with a combination of adhesive and fasteners through factory or pre-marked mounting points. Adhesive alone can flex; fasteners alone can crack the panel. Sand and prep the mounting surfaces thoroughly before application, then follow your vehicle's service manual for fastener spacing and torque specs.

Does this come with brake light cutouts or sensor provisions?

This is a solid front lip under spoiler with no pre-cut openings. Verify your vehicle's OEM bumper configuration and any sensor locations on the existing fascia before final installation to avoid interference.
