Will this diffuser scrape on steep driveways or inclines?

The diffuser extends minimally from the bumper and is positioned high enough for typical driving. Check ground clearance on your specific setup and driveway angles before final installation to ensure adequate spacing.

Does this add real downforce or is it cosmetic?

This is a functional diffuser. The panel channels airflow to create genuine downforce at highway speeds, improving rear stability. It's not purely cosmetic—the design works aerodynamically while delivering the carbon fiber look.

What fasteners do I need to install this?

The diffuser mounts to existing rear bumper attachment points. Verify your vehicle's OEM mounting holes and gather appropriate bolts and clips for your bumper design. Refer to your vehicle's service manual or a detailed install guide for proper fastener specifications and torque values.
