The vinyl on the tails looks really good. I might have to steal that from you, although I might still just tint the whole light.
Going back a few posts, I think keeping the front lip, side rockers, and rear lower half of the bumper satin black will be better, since I think it makes the car look a bit slimmer, if that makes any sense. Side diffusers and a lower rear valence in black would be even better, since it makes the car appear a bit lower. Just my $0.019
