Just installed these.
Overall, the quality feels and looks good, the stitching is tight. They fit really well on the seat, obviously custom made for the camaro. Longevity is an unknown for now. The bottom part anchors seem like they might not stay secured when you move the seat, but we'll see after some time.
There are some things I don't like though.
The holes for the seat belt, although perfectly aligned, have visible white foam areas.
There's no outlet in the rear seat cover for the seat release pull.
