Do I need to drill new sensor or fog light holes?

Reference your vehicle's OEM bumper hole locations before final fitment. The ZR-S profile may require minimal trimming around existing cutouts depending on your specific setup. Test-fit with your lights or sensors before committing to drilling.

What prep is needed before painting?

Sand and prep the surface with your preferred abrasive before applying primer and topcoat. FRP surfaces benefit from light scuffing to ensure proper paint adhesion. Your choice of primer and finish determines the final look and durability.

Will this work with my existing undertrays or air dams?

The ZR-S undertrim profile sits lower than stock, so check clearance with any added aerodynamic components or undertray mounting hardware. Minor trimming of existing brackets may be needed to avoid contact.
