Tre when they were discussed those 3 things were discussed and yes safety was number one issue. They are both optional you dont have to run them ( i dont) we were already allowed a 9 inch so whats a floater? (a SAFER 9 inch) . Ok and the beadlock yes it costs a little more then a regular wheel the purpose of having them was to try to keep cars on the track without blowing a right rear and taking cars out of the race. Neither of the new changes were performance enhancing they were safety enhancing. The only change that was Mandatory was the Raceciever. We hope you come out with your car any of us will help you out to get you out their.
