Will this scrape on steep driveway inclines?

The AF-1 profile sits close to the factory location, so clearance matches OEM specifications. Verify your vehicle's current ground clearance and any suspension modifications before installation — aggressive lowering setups may reduce clearance regardless of diffuser design.

Is this purely cosmetic or does it actually improve downforce?

The AF-1 is a functional diffuser with engineered airflow channels designed to increase rear downforce and reduce lift. You'll feel the aerodynamic benefit at sustained highway speeds, not just visual impact.

How do I maintain the clear coat finish?

Wash regularly with automotive soap and a soft microfiber cloth. Avoid high-pressure washers directly on the weave, and park in shade when possible — UV exposure degrades clear coat over time even with protection. Reapplication of clear coat extends the finish life significantly.
