Are the sensor holes already cut out, or do I need to drill them?

The sensor holes are pre-drilled and ready to accept your factory sensors. No drilling required — just verify hole alignment during installation.

Will this work with a lower valance or belly pan?

That depends on your specific lower panel setup. Test-fit the cover against your existing valance or undercarriage components before final fastening to confirm clearance.

What condition is the chrome finish in when it arrives?

The cover ships with a chrome-finished surface ready for installation. Inspect for any transport damage upon arrival and clean with a soft cloth before mounting.
