Will this fit over my factory fog light cutouts without modification?

The GT300 profile includes pre-molded fog light cutout areas. Verify your vehicle's OEM fog hole diameter and location before installation — you may need to carefully trim or enlarge the openings depending on your factory setup and aftermarket light choice.

Do I need to fill the bumper sensor holes in my OEM lower valance?

If your bumper has sensor cutouts, reference your vehicle's original bumper hole pattern. You'll want to fill or cap unused sensor holes on the factory valance before securing this cover to maintain aerodynamic flow and prevent debris accumulation.

Can I sand and paint this before bolting it on?

Yes — sand the primer surface and apply your chosen base coat and clear before final installation. This avoids masking hassle and ensures clean seams where the bumper meets adjacent body panels. Allow full cure time before handling.
