Will this interfere with my trunk seal or bumper fitment?

No. This lip is designed to sit at the rocker line and integrate with the M-Sport bumper geometry. Verify that your existing bumper is OEM or M-Sport spec before installation — aftermarket bumpers may have different mounting hole locations.

Should I use adhesive or drill through for installation?

This piece works with factory mounting points, so follow your vehicle's service manual for fastener locations and torque specs. Adhesive alone is not recommended for lower lips — mechanical fastening at the OEM points ensures stability at speed.

What prep is needed before I paint this?

Sand and prep the surface with appropriate grit before applying your chosen base coat and clear. Work in a dust-free environment and follow your paint supplier's guidelines for FRP substrates to ensure proper adhesion and finish quality.
