Thanks frank and ryan. I was told sugar but it could be some other additive. I heard 200lbs...whatever that means. I know it will be a surprise to everyone and shop will sell out of the "right" tires. Don't want to be left out to dry. I've done a couple things to free my truck up like stiffer rear springs and sway bar but that was before I heard they did something with the track.
Thanks for the help...been racing for 20 years but just into short course. Know I can be competitive with the right setup. Love offroad now.
