They do make a special carpet for cars that can be shaped to some degree, but it's probably just easier to take the stock carpet and rip the insulation from the back of it and glue it down.

You can mount Sparcos to the stock sliders, I just did it this year. But it's a bitch, and I ended up drilling new holes through the bottom of the seat, since the side mount holes would take way too much fabrication to make decent brackets for. Also it's tough mounting them with anything but the stock sliders because the seats actually sit over a part of the tranny tunnel, so you can't just bolt them to the floor or you'll be hugging the door panels.
