I was looking at the ACC web site in preparation for ordering new carpet and I noticed that there are two different types--Poly and Mass. The mass is $60 more, and I was just wondering what Mass is, why it is higher and is it worth it?
It appears the MASS is the backing on the carpet set. The poly 80/20 is correct for your car. In my opinion, get the best quality carpet set from a company like ACC. The ACC carpet set has the floor dimmer switch plate already installed and you will have a better fit which means less cutting.
