I used these measurements for the P and the E and then I used painters tape under the letters in a straight line and spaced the remaining letters out evenly. I didn't like the template that came with the letters from Suncoast, the letters were to far apart. I also didn't like the way they looked when I tried following the same curve as the Boxster letters. Hope that helps. It takes a bit of patience to get them all spaced out evenly.
