Will this diffuser scrape on steep inclines or driveway approaches?

The Zex style diffuser follows factory body contours and uses OEM mounting points, so ground clearance remains consistent with the stock rear end. Check your typical approach angles against your vehicle's standard bumper clearance — this diffuser does not extend beyond that baseline.

Does this diffuser provide functional downforce or is it cosmetic?

This is a styled diffuser that enhances the rear-end appearance. It follows Zex design language with integrated vanes, but downforce benefits depend on vehicle speed, suspension setup, and overall aerodynamic package — not the diffuser alone. Treat it as a visual upgrade that complements the chassis.

What maintenance does carbon fiber require to keep it looking new?

Wash with mild soap and water, dry thoroughly, and avoid abrasive scrubbing that can dull the clear coat. The UV-protective finish resists fading, but regular cleaning preserves gloss. For minor scuffs, light polishing compound restores clarity without requiring refinish.
