Download instructions. As with all my mods, extract the Main Folder (part 1) to your Nascar Heat folder, then extract the remaining 3 parts into the part 1. I want to give the credit for the chassis to Diamond Race Team. "NOTE" The UI and PAINT were inadvertantly put into folders before I zipped them up. You must take the UI and PAINT out of the folder after you unzip them, and place them into your USMTS 2007 folder in order for them to work. I appologise, I was rushing to get it up before I had to leave for Omaha and for some reason stuck them in folders, when I should have just zipped them up. I would take too much time to delete them from the site and reupload, so just take that one extra step and you should be good to go.........Thanks
