X2............I have sand stars on 10 inch rims and only removed the mud scrapers, no spacers. I can measure mine later if you need offset etc.....You won't need spacers, as the wheels that you can get will be a 4x3, just have to take the mud scrapers off the back of the quad. I can not verify how wide the wheels would be though are though. How wide are the tires you plan on putting on?
