Deviated carpet was offered on 993's & on the newer cars.. not sure if was an option on 986's though. On mine, the red floor mats are newer original Porsche Tequipment. They're a shade or two lighter than the floor carpet, not sure if they all come this way or if it was just a certain batch.. In hind sight, I would have ordered Lloyds mats again. If you wanted to spend the coin, I'm sure black carpet is still available - either through Porsche or upholstery shops, like Classic9Leather.
993 w/ box red + black carpet
981, this one has deviated seat cushions too. Not boxster red though:
