I've got a set of the mirror caps and the carbon spoiler ready to install this weekend. I personally would have preferred mirror cap replacements rather than overlay caps, but I've seen them on a white Teggy, and if you didn't know, you couldn't tell. I actually like that it leaves a body color...
Acura Parts manager here. I took a TLX front lip out in the parking lot and held it up to the bumper on a Teggy.
I'm not saying they lied, I'm just saying it didn't look possible to me.
