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

The HMS lip is designed to sit flush with the lower bumper plane and clears standard undercarriage geometry. Before installation, verify clearance between the lip edge and any chassis components or ground by checking your vehicle's factory service manual for bumper-to-ground dimensions.

Can I install this with adhesive, or do I need to drill mounting holes?

FRP panels like this one are typically bolted to existing factory attachment points on the front bumper. Adhesive-only mounting is not recommended for this style of lip, as it bears aerodynamic load at speed. Verify mounting hole locations on your existing bumper before ordering to confirm compatibility with your setup.

Do I need to sand the primer before painting?

Yes. Sand and prep the surface with appropriate grit before applying your chosen finish. Follow your paint manufacturer's surface preparation instructions to ensure proper adhesion and a clean final coat.
