Do these fenders require drilling or can I use the factory bolt holes?

These are designed to use existing factory mounting points where possible. Verify your vehicle's specific hole locations before final installation — some custom drilling may be necessary depending on your setup, but the G-PR design minimizes modification.

What prep work is needed before painting?

Sand and prep the surface thoroughly before applying your chosen primer and topcoat. FRP takes standard automotive paint finishes well once properly prepped — treat it like any other body panel going into the booth.

Will these affect my tire clearance or suspension components?

The 30mm extension adds width only, not height. As long as your current setup clears the OEM fender without rubbing, these will function the same way. If you run aggressive camber or lowering, verify fitment against your specific suspension geometry.
