i will also say that the ACC install for me was a huge pain! and i would never do it again.. well maybe, but depends on the cirucumstances and maybe some help.. had to trim a good deal and didnt get it in perfect, but i was also kinda rushing it some.. i dont know about the ACS, but the ACC is decent quality if you are willing to put in the time and effort to get it in... and i wasnt really thrilled with the perfect fit with the ACC, but its pretty decent and im happy with my black carpet.. it is holding up very well.
