Do I need to sand the primer before painting?

Yes. Sand the surface with appropriate grit to smooth any imperfections and promote paint adhesion. Follow your chosen paint system's prep guidelines for best results.

Will these diffusers bolt directly to the factory mounting points?

These are engineered to the OEM profile and designed to use existing rear panel attachment locations. Verify your vehicle's mounting holes align with the diffuser tabs before final installation.

What prep work is needed before I install them?

Inspect the rear panel and diffuser contact areas for debris or old adhesive. Clean and dry the surfaces completely. Check fitment against the bodywork before securing—minor gaps may require shims or adjustment of mounting tabs.
