Will this diffuser scrape on driveway approaches or steep angles?

The Vortex profile is designed with minimal extension to avoid clearance issues on typical driving approaches. Before installation, measure your vehicle's current bumper-to-ground distance and account for the diffuser's depth so you can verify clearance matches your typical routes.

Does this provide functional downforce or is it cosmetic?

This diffuser is styled after aerodynamic proportions and complements your rear bumper visually. For measurable downforce, you'd want a full aero package with matching undertray and suspension tuning — a single diffuser alone won't produce meaningful performance gains at street speeds.

What prep is needed before I paint it?

Sand and prep the surface with standard automotive finishing steps before applying your chosen paint system. Use proper surface preparation techniques for adhesion, and follow your paint manufacturer's instructions for primer and topcoat compatibility.
