Will this work with factory fog light cutouts on my bumper?

The 1M design features new lower air vents that differ from OEM. Verify your fog light hole locations before installation and drill as needed to match your existing wiring and lights.

Does this lower valance clearance change compared to the factory bumper?

The 1M styling includes a more pronounced lower air dam. Check ground clearance at your typical driveway angle and any parking lot approach angles before final install.

What should I use to prep the FRP surface before painting?

Sand and prep the surface using your preferred finishing method before applying primer and color. FRP accepts standard automotive primers and paints once the surface is properly abraded and cleaned.
