Anyone tell me why karts don't have a differential? Is it too expensive to make? I believe it would pay for itself. Think about tires, they would last a heck of a lot long if the back wheels can spin separately and would most likely handle a much better. I believe a Torsen differential could possibly work. Anyone have any thoughts? why is hasn't been done? Just wondering. I might try building one for fun. Also it would eliminated the need for the front c brackets to be angled.
