Will this lip interfere with my bumper trim or undercarriage at speed?

No — RSpec lip design sits within the factory bumper envelope and does not extend beyond OEM rocker lines or splash guards. Verify clearance with your vehicle's current front bumper condition before final installation, especially if aftermarket bumpers or lowering suspension is already in place.

Should I use adhesive or drill through the FRP to mount this?

Either method works with FRP. Adhesive alone is sufficient for most street applications and avoids fastener holes. Drilling through and using fasteners provides additional security for track use. Sand the mounting surface and back of the lip before committing to your chosen method — FRP bonds well to clean, prepped surfaces.

Does this cover or interfere with the center brake light?

The RSpec design does not include a brake light cutout — verify that your factory brake light lens has adequate clearance above the lip profile before final installation. Minor fitment adjustments may be needed depending on your specific bumper cover condition.
