Will the diffuser scrape on steep driveways or speed bumps?

Rear diffusers sit lower than most bumper covers. Measure the ground clearance at your driveway approach angle and compare it to the diffuser's mounting depth. If you frequently encounter steep inclines, test-fit or consult OEM ride height specs to confirm adequate clearance before final installation.

Is this diffuser functional or purely cosmetic?

The Ergo design incorporates diffuser blade geometry that follows functional aerodynamic principles—directing airflow and reducing underbody turbulence at highway speeds. It delivers both visual impact and airflow management, though real-world downforce gains depend on vehicle speed and overall setup.

What finish prep should I do before installation?

Carbon fiber ships ready to install, but the surface should be clean and dry. Sand and prep the mounting surfaces on your vehicle's rear bumper to ensure secure fitment. A light protective wax on the diffuser after installation helps maintain the finish against road debris and UV exposure.
