Will this diffuser scrape on driveways or steep inclines?

The three-piece design sits lower than most OEM rear bumpers. Check ground clearance at your vehicle's lowest departure angle before installation — account for suspension height and any load you regularly carry. If you frequently bottom out stock bumpers, this will have similar clearance concerns.

Is this functional or cosmetic?

Forge Works diffusers are styled for visual impact with vane geometry that channels airflow under the rear. They're primarily aesthetic — don't expect measurable downforce gains at street speeds. The carbon construction keeps weight minimal, which is a real advantage.

What finish does this come in?

Ships in raw carbon fiber with visible twill weave. Sand and prep the surface before applying your chosen finish — clear coat is recommended to protect the weave from UV exposure and maintain the glossy appearance long-term.
