Will this clear the road under load on inclines?

FRP diffusers sit closer to the bumper line than aggressive aftermarket designs. Verify ground clearance on your specific vehicle by checking OEM bumper geometry and planned ride height before ordering.

Is this functional downforce or cosmetic only?

This is a styling diffuser designed to complement the rear bumper aesthetic. For measurable aerodynamic benefit, consult suspension and aero tuning specialists regarding your full setup.

What finish preparation should I do before painting?

Sand and prep the surface per your chosen paint system's requirements. FRP accepts most automotive finishes—verify compatibility with your painter before applying color or clear coat.
