| The majority of people/companies running them are doing it to save weight. Some run tag axles, aluminum hubs, even carbon fiber springs all to get the light weight down. Smaller fuel tanks, fiberglass cabs, smaller engines, you name it they'll shave it. They are really expensive, and if they fail alot of times it will wipe out the wheel also. Personally I think they look really cool but I'd rather not have to deal with them. |
