Your fenders are not rolled. Mine on my 2003 S are the same. They would not need to be rolled, and spacers would not be needed, because the 18" wheels yours came with were a factory Boxster option. The 18" wheels that need spacers are for 911s. I have 18x8 and 18x10 Carrera light wheels, which were put on my Boxster by the previous owner and need spacers, because the offset is for a Carrera, not a Boxster.
