Do these bolt directly to the factory fender mounting points?

Yes. These over fenders mount to existing factory attachment locations. Verify your vehicle's OEM fender hardware is in good condition before installation, and use fasteners appropriate for FRP panel thickness.

What prep work is needed before painting?

Sand the surface and clean thoroughly to remove dust and mold release residue. This ensures solid paint adhesion. Follow your chosen paint system's surface preparation steps before primer and topcoat application.

Will these affect my wheel fitment or tire clearance?

The 70mm extension adds width to the fender line. Verify your wheel and tire combo clears the new fender edge at full lock and throughout suspension travel. If running aggressive offsets or wider tires, test fit before final installation.
