Will this scrape on steep driveways or parking lot angles?

The diffuser extends beyond the stock bumper line. Before installation, check your approach angle at home and verify ground clearance during a test fit. Your driving habits and suspension setup dictate how much angle clearance you actually need.

Is this diffuser functional or just cosmetic?

This is a visual upgrade designed to match the Gran Veloce aesthetic. While FRP diffusers can support aerodynamic design, performance benefit depends on the complete rear wing and underbody setup. Treat this as a styling piece that works best as part of a full aero package.

What prep and paint process should I use?

Sand and prep the surface before applying your chosen primer and topcoat. For best adhesion and durability, follow the paint system manufacturer's recommendations for FRP substrates. This ensures color match with your vehicle and long-term finish integrity.
