Will this diffuser scrape on driveways or steep inclines?

The Avera profile adds depth to the rear bumper line without excessive downward extension. Check your approach angle and ground clearance before installation. If you frequently navigate steep driveways, test fit or consult your vehicle's bumper geometry to confirm safe clearance.

Is this functional downforce or cosmetic styling?

This diffuser is designed for visual impact and rear-end character. While the sculpted profile follows aggressive aesthetic cues, aerodynamic benefit at street speeds is minimal. It's primarily a styling statement.

What prep work is required before painting?

Sand the surface with appropriate automotive sandpaper and clean thoroughly to remove dust. Use a quality automotive primer and paint system of your choice. Proper surface prep ensures paint adhesion and a professional finish.
