Will this diffuser scrape on steep driveways or inclines?

Rear diffusers sit lower than the body, so clearance depends on your approach angle and driveway grade. Before installation, verify ground clearance by comparing the diffuser profile to your vehicle's current overhang. Some owners use a slight ramp approach on steep inclines to avoid contact.

Is this diffuser functional or cosmetic?

The Eros Version 1 is designed as a styling element. It provides visual depth and definition at the rear quarter. If aerodynamic function is your priority, validate airflow integration with your existing rear bodywork and any other aero components.

What prep work do I need before painting?

Sand the surface thoroughly to ensure paint adhesion, then wipe clean of all dust. Your paint supplier can recommend the appropriate primer and topcoat system for FRP substrates. Proper surface prep is essential for color match and durability.
