Do I need to prepare the surface before installing these fenders?

Yes. Sand and prep both the panel backside and your vehicle's mounting surface before installation. This ensures proper adhesion if using epoxy or adhesive-backed mounting tape, and clean fitment if using fasteners. A clean, dry surface prevents gaps and shifting over time.

What's the best way to finish these panels?

Sand the surface with appropriate grit to promote paint adhesion, then apply your chosen base coat and clear coat. FRP accepts standard automotive paint and clear coat systems. Ensure proper ventilation and follow your paint manufacturer's instructions for temperature and humidity during application.

Will these fenders affect my suspension geometry or tire clearance?

Over fenders extend outward from the original bodyline. Verify that your current wheel offset and tire diameter allow safe clearance inside the new panel. If you run wider wheels or lower suspension, measure the tire-to-panel gap before final installation to confirm fitment.
