I have had this PORSCHE lettering on my trunk since 2010. At the time, Porsche only put these on the Panamera, so I ordered a set and slapped em on my trunk not thinking much about the spacing cause the letters seemed too widely spaced they way they were on the Panamera I thought. I was happy with the application for all these years until I started recently paying more attention to how the factory has been spacing them wider and at a perceived curve. See them on Boxsters, Caymans, and 911s at recent cars and coffee events on weekends, and they're all spaced wider. Great, now my placement looks all wrong to me now!...I MUST correct this!
Order another darned lettering set. Floss off the old letters, clean off residue with Goo Gone, jury rig a new spacing template based off the one on the lettering strip from Porsche, and wala...all is right in the world again!
