Finally got my ZL1 grill painted and installed it along with Trackspecmotorsports' supplied T3 ports. They were one of only two vendors I could find who had a set that were CF hydro-dipped. The other vendor charged $30 shipping so Trackspec it was!
Really pleased how they turned out. Didn't use the 2-stage adhesive supplied though, the special gun was $66 from amazon. Talked with ACS and they said any urethane glue should do so I used the 3M 8609 window-weld glue as it was readily available and worked with a standard caulking gun.
I also did not want to pay $100 for ACS' mesh. I had a roll of diamond mesh I got at a arts/crafts store, plastidipped it black and glued it to the backside of the ports.
After I took the last picture I saw that the LEDs were coming loose, that sucks but easy fix. Thanks to John at Track Spec Motorsports for letting go of their last set carbon fiber ports. He mentioned they might make more if the demand was there.
