Do I need fasteners to install this, or does it come with hardware?

The bracket itself is included. Hardware needed for final assembly and mounting to your license plate is not specified — you'll want standard stainless steel bolts and a plate-to-bracket kit on hand before install.

Will this bracket fit with an aftermarket front bumper or splitter?

This is designed around factory mounting points on the OEM bumper cover. Test-fit with any aftermarket front end before committing to ensure clearance and alignment.

Does the bracket need any prep or paint before I install it?

It ships finished in black powder coat and is ready to bolt on as-is. No sanding or prep required unless you prefer a different color or have specific aesthetic needs.
