Since you have silver as well...
These are my GT3 MK2 style side (fiberglass $400 from precisonporsche.com) skirts on 18" Carreras. Most people have the more expensive polyurethane MK1 style because the factory didn't make the MK2 style for the Boxster. Fiberglass for side skirts is ok in my book, rear and front bumpers not so good.
The GT3 front bumper which has been shamefully sitting in storage for over a year is going on when I have my windshield replaced this month. This guy put the nifty GT3 RS intake holes and meshing to with his silver hood crest. The factory front bumper can be had for another $900. Not including labor, less than $1500 is well worth it and a total transformation in me book. Will definitely help distinguish your car when you sell it from the sea of other silver boxsters.
