Will this bolt straight to my car or do I need new hardware?

Mounts directly to factory holes — you'll use your existing fasteners. Grab your plate's current hardware and you're done.

Does this come painted or do I need to prep it?

The bracket arrives ready to install. If you want to match your bumper color, light prep and a touch-up coat works fine, but it's not required for function.

Will this work if my front bumper has been replaced or repaired?

As long as the factory mounting holes are intact and aligned, you're good. If your bumper's been heavily modified or the holes don't line up, test-fit before committing to installation.
