I have a pair of brand new rear reflector 20% tint film. Perfect for a black Z4. I thought about installing them on my silver-gray, but decided that they wouldn't really work well on my car so I'm just gonna get my reflectors painted silver gray.
They're self adhesive and installation is easy (I installed tail-light tint film on my M myself).
$10 USD shipped.
