Will this interfere with the trunk seal or rear bumper fitment?

No — this is a front lip and sits at the lower front bumper edge. It's positioned forward of any trunk or rear assembly and will not affect those fitments.

Does this require drilling into the bumper, or is it adhesive-mounted?

The three-piece design integrates with existing M-Sport bumper mounting points. Verify your bumper's current fastener layout before installation to determine if additional fasteners or adhesive prep is needed for your specific setup.

Will the clear coat protect the carbon fiber from UV exposure long-term?

Yes — the applied clear coat is designed for UV protection. Over time, exposure to direct sunlight may require periodic wax or ceramic coating application to maintain the finish, especially if the car is parked outdoors regularly.
