Do these fenders work as a standalone kit, or do I need other parts?

These are designed to integrate with a complete wide body kit. You'll need the full kit — front fenders, side skirts, and any other components — for proper fitment and appearance. Installing only the rear fenders without the complementary pieces will leave gaps and misaligned panel lines.

What prep work should I do before painting?

Sand and prep the surface with your preferred grit, then apply your chosen primer and topcoat. FRP benefits from a clean, smooth base before any paint application. Follow your paint manufacturer's recommendations for primer type and application method for best adhesion and finish quality.

Do these fenders come with mounting hardware?

Hardware is not included. You'll need to source fasteners appropriate for your mounting method — bolt-on or adhesive attachment — based on how your wide body kit is designed to connect to the vehicle structure. Reference your wide body kit documentation for the correct fastener specifications.
