To remove the stock mats you'll first need an assistant! Using a heat gun carefully heat a small area at a time and pull back on the mat until you get it all, that's it and there's no other way that i know of. After that i sprayed WD-40 over the entire platform and let it "soak" the adhesive off. Using a very stiff plastic scraper remove the glue. Keep doing this until all gone. I then used a scotchbrite pad to rough up the surface and used alcohol to finish off. Apply your pad.
