Do these require drilling or do they use factory holes?

They mount at factory attachment points — no drilling necessary. Check your OEM fender for existing holes before assembly and verify hole alignment with your panels before final fastening.

What prep is needed before I paint?

Sand the surface and clean thoroughly to remove any dust. Apply your chosen primer and paint system directly over the prepped FRP. No additional sealer is required unless specified by your paint manufacturer.

Will these clear my current wheel and tire setup?

Over-fenders extend the body line outward. Measure your current wheel offset and tire sidewall before installation to confirm adequate clearance — especially if running aggressive wheel fitments or lowered suspension.
