Will this interfere with my trunk seal or weatherstripping?

The J-Spec profile extends minimally beyond the bumper line. Verify clearance with your trunk opening before final fastening. If needed, adjust mounting angle slightly or trim weatherstripping to accommodate the new diffuser position.

Can I use adhesive instead of drilling through the bumper?

This diffuser is designed for bolt-on mounting through existing OEM bumper holes. Adhesive-only mounting is not recommended — fasteners ensure stability at highway speeds and protect against road vibration. Drilling is minimal and uses factory-marked points.

What prep work is required before painting?

Sand the surface with medium-grit sandpaper to ensure paint adhesion, wipe clean of dust, and apply your chosen basecoat and clear coat. Avoid moisture exposure between prep and finish application.
