New Carpet prep

I didn't add anything extra to my Challenger. The jute is all the factory used. You're way ahead of the game if you're installing a Dynamat type material. I would suggest taking the carpet out of the box an putting it in the sun. The carpet seems to lose its shape if it's stored in a box too long. As soon as my Challenger carpet arrived, I took it out of the box so it wouldn't lose its molded shape.
