Will this fit with my OEM fog light cutouts?

The 1M design includes integrated fog light openings. Verify your current fog hole spacing and diameter against the bumper's cutout locations before finalizing fitment — OEM sensor holes may require slight repositioning depending on your existing setup.

Do I need to modify my lower valance or air dam?

The 1M profile sits slightly lower and extends forward compared to the factory bumper. Check clearance between the new bumper's lower edge and any existing air dam or splitter. Minor trimming of the valance may be necessary to avoid contact.

What prep work is needed before painting?

Sand the surface with appropriate grit to promote paint adhesion, then clean thoroughly to remove dust and oils. Apply your choice of primer and paint system from there — the gelcoat foundation accepts both OEM and aftermarket finishes.
