I have personally tested this and we found no difference between matte paint/vinyl or oem paints. Also, there was no difference we found between front plates or no front plates. Speeds were ranged between 25 to 65 mph.
Backround: Military police officer with access to different types of radar equipment, and plenty of friends with customized vehicles.
Take it for what it's worth, but hope it helps.
