Hey all. I'm in the process of replacing (actually installing over...) my old carpet with a new ACC kit. I'm sure some of you have done it, so any advice/help is greatly appreciated.

I'm having some trouble with the fit...The "molding" seems less like definite areas, and more like recommendations of where it's supposed to be. It's also grossly oversized-I can't even get it in the car into a position to see where I need to cut or make holes. I know they purposefully make it larger, but it seems a bit excessive to me.

There are what appear to be mold lines, but I'm not sure if I should just go ahead and cut them out or not. I've attached pictures showing the lines.

The carpet for the driver side should have that rubber pad to reduce wear. That will help with alignment (on that side at least), and then will help give you some 'markers' to figure it out for the passenger side.

If you lay your old carpet over the new stuff and do you best to center/align it, you can then trim back a lot (not all) of the extra. Leave at least a few inches all the way around for final fit/finish and cutting.

Some of the lines in their carpet is because they take it out of the mold and fold it up to store it before it fully cools. Someone once told me a customer could contact them and ask them to leave one to get 'cold in the mold', but I didn't have any luck when trying to do that. So I just got it through RockAuto.

Last option, if you have the center console out, and leave the passenger seat out, auto upholster places will do it fairly cheap. I was quoted 125 to install mine professionally with said prep work done (and not needing to do the pre-trim on the carpet).

I did my Corvette two years ago. Read a long post about leaving the new carpet from ACC inside the HOT Car for a whole day, then installing it at night. the carpet will be really soft and extremely flexible. Trying to put new carpet over the old carpet seems like a recipe for big trouble. Use long pointed AWLS to locate all holes needed in the new carpet, (seats, seat belts, etc.) then use a HOT POINTED Soldiering iron to make the holes, so the carpet wont run. Make small cuts and go slow, Remember “once the carpet is cut you can’t put it back.” Try and leave the carpet as long as possible. Go slow, and it will look great, if you rush trouble will follow.
