Are there sensor or fog light holes cut into this bumper?

This bumper ships as a solid panel. Before installation, reference your vehicle's OEM bumper hole locations to determine if cutting is required for fog lights or parking sensors. Drill or cut openings to match your existing setup.

What surface prep is needed before painting?

Sand the surface lightly to improve paint adhesion, then clean off dust. Apply your chosen automotive primer and paint according to the paint manufacturer's instructions. FRP accepts standard automotive finishes without additional sealing.

Will this fit with my factory lower valance or splitter?

This bumper is designed as a complete front-end panel. Check your current lower valance or splitter dimensions against the M3 profile before ordering to confirm compatibility with your existing aero setup or plan for replacement.
