Will this scrape on inclines or driveways?

The KT profile sits at factory height, so clearance matches your OEM setup. Check your existing rear bumper clearance on steep angles before installation to confirm your vehicle's approach and departure angles work with your suspension setup.

Does this add functional downforce or is it cosmetic?

This is a styling piece. The KT design creates visual aggression and depth at the rear without introducing aerodynamic load. For functional downforce, pair it with a purpose-built rear wing or splitter system.

Should I apply clear coat to protect the carbon finish?

Carbon fiber benefits from UV-protective clear coat to maintain the weave appearance and prevent oxidation over time. Sand and prep the surface lightly before applying your chosen automotive clear coat or protective sealant.
