Will this diffuser scrape on steep driveways or inclines?

The three-piece design allows you to assess ground clearance before full installation. Test fit the rear sections and measure your vehicle's approach angle to confirm adequate spacing. If you regularly encounter steep grades, verify clearance with your specific suspension setup and driveway pitch.

Is this diffuser functional or purely cosmetic?

This is a styling piece that follows GVR's design language. It complements the rear end visually and contributes minimal aerodynamic effect at street speeds. For genuine downforce performance, you would need a larger, ducted rear wing or comprehensive aero package.

Should I polish or wax the carbon fiber after installation?

The clear coat finish is designed to seal and protect the weave. Maintain it with regular washing and a UV-resistant car wax or ceramic coating applied over the clear coat. Avoid abrasive compounds that could scratch the protective layer.
