Will the diffuser scrape on steep driveway approaches or speed bumps?

The Sceptre design sits at the rear fascia line, so clearance depends on your suspension setup and approach angle. Before installation, test-fit the assembly and drive your typical routes to verify ground clearance with your vehicle's current ride height. Adjusting suspension or adding small spacers can prevent contact if needed.

How much prep work is required before painting?

Sand the entire surface to smooth out the Raw FRP finish before applying primer or base coat. This ensures proper paint adhesion and a professional look. The exact grit sequence depends on your paint system — reference your chosen primer or paint manufacturer's surface prep guidelines.

Does this diffuser provide functional downforce or is it purely visual?

The Sceptre profile is a styling enhancement. While the angled blade geometry mimics performance diffuser lines, aerodynamic benefit at street speeds is minimal. It delivers the aggressive rear look without requiring additional bracing or reinforcement — ideal for visual customization.
