good price for the skirting. Its usually $800 unpainted.
The bumper is the 1st generation 996 GT3 bumper which was sold later
as the aerokit II for the Boxster.
I bought my GT3 bumper from an ebay seller 'DE parts'. They listed it
for $900.
p.s. those tech art wheels make a huge difference
you can add the SuperCup lip spoiler from the 2nd Generation 996 GT3
as seen here to the 1st generation GT3 front bumper with GT3 RS inlets and meshing.
