Nissan Silvia S14 OEM Carpet Floor Mats 240SX JDM. Floor mats were originally equipped on a RHD JDM S14 Silvia. Finding original S14 Silvia floor mats in this condition is extremely rare. Nissan will never sell floor mats again, these are 25-30 years old. You can restore engine parts, plastics and metal. Fabrics and carpeted parts cannot be restored to mint condition like these. These floor mats belong in a low mileage all original S14 Silvia. These will also fit USDM S14's pretty well, just keep in mind the metal hook that holds the JDM driver side mat in place is on the opposite side since these were intended for a RHD car.
