Yes, I'm resurrecting this thread.... I feel it's important to have a written record of this stuff so that the corporate "suits" can't keep saying nobody else has any issue....must be your fault. I think the manufacturers need to hear what's going on.
As you have read in this thread, I put new Mass Backed ACC carpet in my convertible in the spring of 2008. I was pleased with how easy it was to install. The mold was strong and tight. There were no wrinkles or other things other than the tranny tunnel was a bit large/high, but not a deal breaker for me at the time. I have to believe it was the 80/20 loop b/c it gets very fuzzy easily and doesn't wear well at all. I suggest never wearing shoes in a car with this carpet and never vacuuming it hard if you want it to last.
Fast forward to March/April 2010 - I'm doing my '65 fastback carpet now. I can report that the black RAYLON carpet seems to be much better with respect to wear. It does not yet appear to get fuzzy and I've been working it hard trying to get it to lay down/fit. Still no fuzzies. Time will tell about fading.
The bad news is that I had to give up on my first set and order a new one. The back fit OK (maybe, as I haven't installed the interior panels yet to confirm. The front fit was terrible. Couldn't get the wrinkles/creases out, way too large over the transmission hump (I have a 4 speed). After wasting an entire day, I gave up. If I hadn't had such an easier install on my convertible I would have thought I was doing something wrong.
The current second set was a little better in regards to fit. I think they left it in the mold longer. Still not as good as my convertible experience. Wrinkling/poor fit in the heel/toe pad area, and over the hump were large long "dents" in the carpet and backing. I spent days and hours trying to relax things. Heat guns, damp towel ironing, etc...I couldn't fix it. The heel pad doesn't lay down flat near the tunnel area, and never will (no problem here on my 'vert carpet) Perhaps it would settle after being partially installed for a while? Well, it's impossible to partially install this without cutting a good 4-6 inches off the ends in all 3 trimmable directions. The shifter area also needs to be cut. Well, have fun returning cut carpet...
This second set is now installed, but not without the visible problems of the dents, and wrinkles on the trans tunnel area. Where the front overlaps the back, the front has a sort of serged edge. Well, my black carpet should have a black edge, no? I see metal like stitching all along this highly visible edge with seemingly no yarn or other black material covering it up. There are also a few areas were the nap is not even and I have a few "high" loops that stick up way past the rest. I have little/faith that a 3rd set will be any better as I was assured the vendor rep personally inspected this set prior to shipping, and it was custom made for me (twice). At this point, I'm giving up and will have to live with what I have. Thank goodness it's a driver.
Still, I find the consistency and quality control of this carpet company to be highly inadequate. I think we need to voice our opinions with real world feedback and insist on better carpet. I honestly hope your installation experience goes well. It seems to be hit or miss... I still think the mass backing is a good idea when it works well, but if there is any problem with the carpet, the extra mass backing exacerbates the problem.
I have also read elsewhere that Trim Parts makes carpet. I have further read that they are both using the same carpet, supplied by Dorset. I can't confirm this as fact, but it's what I read.
