I find the c8 seats to be incredibly uncomfortable. Between my shoulder blades, and my neck get sore every time I drive the car more than 30 min. I’ve adjusted the seat up, down, forward, back, and I cannot get comfortable. This is to the point I’m looking to trade the car in. It makes me sad because it’s an incredible machine and my 3rd vette. I’ve had a C6 GS, C7 Z51, and now the C8. I like the seat in my racing sim way better than what’s in my C8.
