I did the same as Danny. The crest is in the front and the script in in the back. It does, in my opinion, look to busy with crest and script on the front and back. I offset this by adding a Porsche grille badge on the back.
I used the emblem tape because it could be corrected if I did it wrong.
You can emblem tape the script. It took two versions of an exacto knife and a sh*&load of patience. The hardest part of the emblem tape on the script is making sure you cannot see the tape through the script (loop of the "P", "O" and loop of the "R").
