Will this interfere with my trunk seal or bumper attachment points?

This lip mounts to the lower fascia and does not contact the trunk. Verify clearance with your bumper's existing attachment points before final installation, as your bumper may require slight repositioning depending on fitment tolerance.

Does the air dam block the brake light cutout on my bumper?

The HM-S profile is designed to sit below the brake light assembly. Check your bumper's reflector and sensor location before installation to ensure no overlap; if your bumper has custom cutouts, confirm the air dam clears them.

Should I use adhesive or drill through the mounting tabs?

Both methods work depending on your preference and existing bumper setup. Adhesive offers a cleaner install with no new holes; drill-through provides permanent security. Choose based on whether you plan to keep the bumper or swap it later. Ensure the mounting surface is clean and dry before applying any adhesive.
