How do you folks with longer names fit your name on the rear quarter window? 3" height is pretty big.
Name decals.

Just change your name… 
Seriously, measure the area and have your graphics guy make the letters as big as possible, so they fit on the window.
You know that driving a Spec E30 car makes you famous and you don’t want the autograph seekers to wonder about your name…
