Will this diffuser scrape on driveways or steep inclines?

The diffuser extends from the factory bumper line, so clearance depends on your vehicle's existing ride height and approach angle. If your R sits at stock height, verify ground clearance at your typical driveway angle before final installation. Lowered setups will require additional caution on steep ramps.

Does this add functional downforce or is it purely aesthetic?

This is a styling piece that follows RZ design language. Real downforce requires precise engineering of airflow and panel geometry—this diffuser delivers the visual aggression of the RZ look without claiming aerodynamic function. Install it for appearance and the weight savings FRP provides.

What prep work is required before painting?

Sand the surface and apply your chosen topcoat system. Follow your paint supplier's recommendations for primer and clearcoat compatibility with FRP substrates. Proper surface prep ensures adhesion and long-term finish durability.
