Do these fenders bolt directly to my existing fenders or do I need to modify the original panels?

These over fenders mount over your OEM fenders without cutting or drilling through factory metal. Verify your vehicle's existing mounting points before assembly and use appropriate fasteners rated for FRP-to-body attachment. Your service manual will confirm available mounting locations.

What prep work is needed before I paint these?

Sand the surface with appropriate automotive-grade abrasive before applying your chosen primer and topcoat. This ensures paint adhesion and a clean final finish. Follow your paint manufacturer's surface prep guidelines.

Will these fenders affect my tire clearance or wheel fitment?

Over fenders add material outboard of your OEM panel line. Before final installation, test-fit your wheel and tire combination (especially at full lock) to confirm adequate clearance. Spacers or wheel offset changes may require clearance verification.
