Hello Tony,
Go to this link in the ERA WEB site and there is a complete diagram for the stipes from the lower front to the lower rear.

Have fun...I used these dimensions on my car and added the little stripe outside of the main ones. If you follow this the stripes will look the same width for their entire length...eliminates the doppler vision effect.
