I don't think spinners would work too well. The only reason why they work as well as they do on real cars is because they're so heavy and they're mounted on ball bearings. You could theoretically have ball bearings that small, but it'd be really expensive to make, plus maintaining them would be a real pain. I've heard of real ones getting gummed up with road salt, dirt, ice, you name it. Just imagine how much dirt your bit picks up. Now think about having that dirt in your expensive spintek knockoffs
