Will the diffuser scrape on steep driveways or inclines?

The F1-style profile is designed to sit close to the rear bumper line without extreme extension. Verify clearance against your vehicle's current ride height and suspension setup before final installation, especially if you run lowered springs or coilovers.

Is this diffuser functional or cosmetic?

This is a functional F1-style diffuser engineered to manage rear-end airflow separation at higher speeds. It complements the factory aerodynamic package and is most effective when the full rear underbody is clean and free of debris.

How do I protect the carbon finish long-term?

The clear coat provides UV protection, but regular cleaning with a microfiber cloth and mild soap keeps the weave pattern visible. Avoid abrasive wheel cleaners on the carbon surface, and consider a dedicated carbon care product to maintain clarity over time.
