I received clarification from Harlan, after seeing that the Edge Red calipers were glossy at the HTC reveal, that Edge Red ones are no longer a satin finish (as I saw/pictured at 7.18.19). This means the calipers are being shown at mobile dealership displays and other special C8 presentation events were earlier pre-production, subject to change, versions. Here is a picture of the Edge Red I took at the HTC’s 10.2 reveal, showing it is glossy, and when while I taking it, it was such a visual change, I asked two people around me and they too confirmed is was a glossy finish not a satin one we earlier we seeing Lastly, Harlan confirmed that the HTC and the coupe‘s calipers are identical to each other.
