Will this diffuser scrape on driveways or steep inclines?

The C63-style profile sits lower than the OEM bumper. Before installation, confirm clearance on your typical driving surfaces and parking angles. Adjust the mounting height if needed to suit your vehicle's ride height and driving habits.

Is this diffuser purely cosmetic, or does it provide functional downforce?

This diffuser is styled after the C63 design and delivers visual impact. Functional aero performance depends on total vehicle setup—suspension, splitter, and body modifications working together. Use this piece as part of a complete aero package for best results.

What prep work should I do before painting?

Sand and prep the surface thoroughly before applying your chosen finish. Refer to your paint supplier's guidelines for surface prep, primer type, and topcoat application. Proper prep ensures a durable, factory-quality result.
