Will this diffuser scrape on steep driveways or inclines?

The diffuser hangs below the rear bumper line. Check your vehicle's current ground clearance and driveway approach angles before installation. Most owners with stock suspension clear typical residential slopes without issue, but steep ramps or steep driveways may require caution at extreme angles.

Does this provide functional downforce or is it cosmetic?

This is a style-matched diffuser designed to replicate LP570 factory geometry. Real-world aero gains depend on vehicle speed, suspension setup, and overall bodywork configuration. It functions best as part of a complete aero package rather than as a standalone downforce solution.

What finish preparation should I do before installation?

The carbon comes with clear coat applied. Sand and inspect the mounting surface on your vehicle before bolting down. If you plan to add additional coating or polish the weave, prepare the diffuser panel with appropriate abrasive prep and follow your chosen product's application instructions.
