Ive spent hours searching for the full version of this program that you normally have to purchase, but just recently found it at www.tirecraft.com. Go to the custom wheels section and select the softwheels icon, then press the "nextwheels" button. They just recently added the ss/sc to the list of vehicles. It includes multiple wheel manufacturers such as adr, motegi, american racing, etc, etc, etc. You can make the car literally any color you want and even LOWER it. You can put any wheels you want on it, but only the ones with the check mark will fit (there are around 10 wheels total in the entire program that fit this crappy bolt pattern.) Good luck and have fun!
