Do I need to drill new mounting holes or can I use existing OEM locations?

The panels are designed to align with factory mounting points on the original fender. Reference your vehicle's OEM fender hole locations before installation to ensure accurate fitment and to determine if you need additional fasteners for the extended flange.

What preparation is needed before painting?

Sand the surface thoroughly to remove any dust or contaminants, then apply your chosen primer and finish coats. Starting with a clean, properly sanded surface ensures better paint adhesion and a professional look.

Will the extra 25mm width cause tire clearance issues?

The fenders sit outboard of the original panel, so your tire and suspension geometry remain unchanged. Verify your current wheel offset and tire sidewall clearance against the factory fender before installation — the extra width is purely cosmetic extension.
