Do these over-fenders require modification to my existing fenders?

No permanent modification is needed. Over-fenders mount on top of the existing panel. Reference your vehicle's OEM attachment points to determine the fastening method that works best for your setup—bolt-on, adhesive, or a combination approach are all viable depending on your long-term plans.

What surface prep is required before painting?

Sand the surface with appropriate grit to achieve a smooth base, then apply your chosen primer and topcoat system. FRP accepts standard automotive paints and clears. Verify compatibility with your paint supplier before application.

Will these affect my tire clearance or suspension geometry?

Over-fenders add width to the wheel arch opening. Confirm your tire size and any suspension modifications will not cause contact with the new fender line. Measure your current wheel/tire setup against the new profile before final installation.
