Do these over-fenders require drilling or cutting into my factory fenders?

No. These panels are designed to bolt to factory mounting points without modification to your existing fenders. Verify your vehicle's OEM hole locations before assembly to ensure alignment.

What prep work is needed before I paint these?

Sand the surface with appropriate grit to achieve a smooth base, then clean thoroughly to remove all dust. Follow your paint manufacturer's instructions for primer and topcoat application over FRP.

Will these fit properly with my factory wheels and suspension setup?

Over-fenders add width to the front end. Confirm your tire and wheel fitment will not contact the extended panel edges. If you run wider wheels or lowered suspension, test clearance before final installation.
