Will this diffuser scrape on steep driveways or inclines?

The AF-2 profile is designed for street use with standard ride height. Check your vehicle's current rear ground clearance — if you already bottom out parking ramps or steep inclines, this diffuser will follow that same geometry. Measure from the OEM diffuser edge to ground and compare before installation.

Is this for functional downforce or visual upgrade?

This is both. The AF-2 shape generates real aerodynamic load at speed, improving rear-end stability under acceleration and braking. It's not purely cosmetic — the vane design accelerates air flow and creates pressure differential. You'll feel the benefit at highway speeds.

What finish should I use on exposed carbon edges?

UV-protective clear coat is recommended to preserve the weave and prevent UV damage over time. Sand the surface lightly before applying your chosen finish. If you prefer matte or gloss, that's your call — just seal it to keep the carbon looking fresh.
