Thanks guys glad you like it, I thought they came out well, the silver center is a bit metallic with a small checker pattern that really looks good. I don't know about the Z8 but with the large holes in the floor behind the seats of the Z6 this helps to keep things from hitting the ground, I'm going to work on those holes next month, mostly to keep dust and noise down.
Coloradocrawler, my upholster made a sleeve that he slid down over the top of the frame instead of using screws to hold the vinyl in place, this created a map pocket behind the seat that is a good place for a wallet or anything that you want to keep hidden, I thought about using a piece of ABS plastic but went with the vinyl to create a small belly in the front as well as the pocket in the back.
