Those came from JonB at PartsRack several years ago. They fit Gen III and Gen IV Vipers. After the fronts were introduced,, rears were added.They were well made, not cheap, and sold out a long time ago.
Of course, you could still make an inquiry...who knows what may transpire??!!!
Viper specialty sells a similar set, though not in CF as far as I know. I bought a set of them a long time ago because they were low profile and almost invisible to the ***** eye while still offering rock protection. Guess it depends if you are really after the CF look or more just the protection.
