Just got these...
The Good: The "Z"'s look great -- the chrome looks OEM quality. Very nice, especially for the price.
The Bad: Don't know about the cf backing, but the plain black backing appears to be paper?! It doesn't lie very flush, and deforms against the car when affixed.
Also, how well will this backing survive rain or washing?
The backing needs to be hard PLASTIC.
I'd really like it if EVO-R could send me a fresh backing that I can affix if I want to of painted plastic. Otherwise, I'm going to have to chop up a coffee can lid or something.
I don't know how much a plastic backing would add to the cost, but it REALLY needs it.
I give this product 8.5/10. It could easily be 10/10 with a better backing solution.
