Will this interfere with my trunk seal or undercarriage?

The diffuser mounts to the rear bumper structure and sits behind the OEM fascia. Measure the depth of your stock bumper and any existing aero before ordering to confirm clearance with your exhaust tips, undertrays, or diffuser elements you may already have installed.

Can I install this without drilling into the bumper?

Installation method depends on your bumper design and mounting strategy. Verify your bumper's existing holes or reinforcement points before committing to drill-through vs. adhesive bonding. Many builders use a combination — adhesive for primary contact and self-tapping fasteners through existing mounting bosses for security.

How do I maintain the carbon fiber finish?

Wash with mild soap and water, dry with a soft cloth, and avoid abrasive compounds or pressure washers on the weave. The clear coat protects the fibers from UV damage, but avoid prolonged direct sunlight when parked. If the finish dulls over time, a light hand polish with automotive wax restores gloss without stripping the protective coat.
