Will this diffuser scrape on driveways or steep inclines?

The GT Spec profile is designed for moderate ground clearance. Check your vehicle's current rear bumper height and measure any driveway angles before installation. Minor scrape risk exists on steep approaches — verify clearance at your most challenging entry points.

Is this functional downforce or cosmetic?

This is a styling diffuser. It delivers the GT Spec visual proportion and profile. For measurable aerodynamic benefit, confirm your full setup (splitter, wing, body modifications) with an aero specialist — diffusers work best as part of a complete system.

What prep work do I need before painting?

Sand and prep the surface per your chosen paint system's requirements. Consult your paint supplier for grit recommendations and primer type based on your top coat. Proper surface prep ensures long-term adhesion and finish quality.
