I did it to mine since I replaced my damaged front bumper with the 1M replica. I'm still thinking about redoing that one for the version with the fogs (there's two different types)
But overall I'm very happy with the 1M rear. I've been waiting for my blacklines I ordered from ECS to arrive before I do a full photo shoot.
But this is how mine looks after I had a custom quad setup fabricated. Overall, I think it looks great, it believe it adds to the car and really doesn't throw things off much.
