I did the Madico Ceramic 50% back 20% front and it looks nice. A neighbor did 20% all around on his black e46 and it looks REALLY nice. The 20% would be hard to see from a cops perspective and because it's lighter than the back they overlook unless they are out for you.
Most of the cops I have been pulled over (mostly CHP) are car guys and they don't hassle me about the no front plate and tinting (12 years on the M3 with no comments). My wife got dinged for no front plate on the Odyssey by a meter reader (Too F'ing lazy to walk to the back of the car for the plate)
