Do these louvers need to be painted or primed?

The louvers ship primed and ready to paint. Sand lightly with 220-grit before applying your chosen top coat to ensure proper adhesion.

Will these fit the convertible or the hatchback?

These are engineered for the coupe body only. Convertible and hatchback models have different glass geometry and mounting points — do not use on other body styles.

What fasteners are required to mount them?

Hardware is not included with this assembly. You'll need to source fasteners compatible with your factory mounting points — check your vehicle's service manual or test-fit first to confirm what you need.
