Will this diffuser scrape on driveways or steep inclines?

The diffuser extends minimally from the rear bumper. Check your current ground clearance and compare to the factory bumper profile. If you already run low, test approach angles in your driveway before final installation to confirm fitment with your setup.

Does this diffuser provide functional downforce or is it cosmetic?

This is a styling panel styled after the Tando design. It does not include aerodynamic ducting or internal channeling for airflow. Install it for the look — don't rely on it for performance gains.

What hardware is needed to install this?

The diffuser uses existing factory mounting points. Bring basic hand tools and fasteners compatible with your stock rear bumper attachment system. Refer to your vehicle service manual for torque specifications and bolt sizes to ensure proper installation.
