Will this interfere with the trunk seal or lower bumper gaps?

This front lip is designed to bolt to factory mounting points and maintain OEM gap tolerances. Before installation, verify clearance between the lip edge and your bumper cover — some fitment variations occur due to factory tolerances on the fascia.

Should I use adhesive or drill new mounting holes?

This lip is engineered to use existing factory mounting points on the front fascia — drilling is not required. Fastener specifications vary by application; reference your vehicle's service manual to confirm bolt sizes and torque values.

How stable is FRP at highway speeds?

FRP panels are rigid once properly secured to factory mounting points. Confirm all fasteners are tight before driving, and inspect the mounting area periodically to ensure no movement or vibration develops during use.
