Will this diffuser scrape on steep driveway inclines or parking lot entrances?

The diffuser extends beyond the OEM bumper line, so verify ground clearance on your specific suspension setup before installation. Lower vehicles or aggressive suspension angles may need ramp awareness. Test fit the assembly in your driveway to confirm your typical entry angles won't cause contact.

Does this provide functional downforce or is it cosmetic?

The RSO Moto design includes blade geometry that is styled for visual aggression. Real downforce performance depends on vehicle speed, chassis aerodynamics, and splitter angle — this diffuser is best viewed as a styling statement paired with your overall aero package rather than a standalone performance upgrade.

What prep work is needed before finishing the diffuser?

Sand and prep the surface before applying your chosen primer or paint. The FRP arrives ready for finishing but requires surface treatment to accept color coatings. Use standard automotive prep methods and your paint system of choice to ensure proper adhesion and durability.
