Thought for 14s
The "Prefix Special Edition" (also called Prefix Aero Package) refers to an aftermarket aerodynamic upgrade offered by Prefix Corporation for 16 of the 100 special 2006 Dodge Viper SRT-10 VOI.9 (Viper Owners Invitational .9) Edition coupes.

These cars are all Stone White with blue stripes, individually numbered #1–100, and the Prefix package added a carbon-fiber front splitter (chin spoiler) and a large adjustable carbon-fiber rear wing (with aluminum stanchions/endplates), developed for added downforce. It was a $7,200 option at the time. Some cars also received other upgrades like Mopar Performance Packages.

Prefix issued Certificates of Authentication with the full list of 16 VINs/serial numbers for these cars (often included in documentation packets with window stickers). Full individual VINs aren't widely published publicly for privacy/ownership reasons, but the # list above is consistently referenced by owners in club discussions.

If you're looking for a specific car's details, more documentation, or to verify one against the Prefix list, checking the Viper Club of America forums or contacting Prefix Corporation directly would be the best next step, as they handled these packages. Let me know if you have a particular # or VIN!
I do have those VIN's # of relationships, however, they are just not ready for public release as I have not finished with some due diligence.
