I got mine from Suncoast and installed them with my 11 year old son in about 5 minutes - with the bonus that he can now say he helped change them out. (And I'm NOT one to mess around with the car in general, though doing the side markers has me thinking that maybe I should consider doing more...)

It's shocking that Porsche ships here with the orange markers at all - they're just so wrong. Hell, even my wife commented immediately that the clears look much better, and that was after mocking me for ordering parts before the car even showed up!

Wherever you get them from, just make sure you do - and enjoy your car!
