I really like the effect you are using, as I use it on my site. However, I would like to offer a suggestion to fix your header. Your repeating header image doesn't align correctly on a lot of different resolutions.
Code:
#toplogo {
height:80px;
margin:0px;
background:#636464 url(../../images/carbonfibre2/body/cback.gif) repeat-x;
}
Change this code to:
Code:
#toplogo {
height:80px;
margin:0px;
background:#636464 url(../../images/carbonfibre2/body/cback.gif) repeat-x top right;
}
Now you need to make your repeating backgorund image (

) match up with the right side of your logo.

<-- Start your repeating bg image on this side.
Tip. To easily make the stripes match perfectly on your new image of cback.gif, take the width of your current cback.gif and use it as the width for your new image. Doing that regardless of what your slice looks like should work. I uploaded a small screen shot to give you an example.
Nice style btw! Keep up the good work.
