I had the GT3 rep seats in my old 996 a couple of years ago. I had the seat shells ultrasonically tested at work to see what the quality of the carbon was and it's actually surprisingly good with regards layup, ply drops and embedded structures. China can do some decent carbon (as witnessed by the fact that Chinese carbon companies are now OE to Aston and Porsche amongst others). I wouldn't worry about them the way people on this thread are.
Good enough for me.
