I spoke with a Team Driver this weekend at the race. He said they are definately working on a new car, but he couldn't tell me anything about it. He did say they are working on new AE Shock Towers, and he also said that Extreme Racing is making a great carbon tower for the RC8T rear tower upgrade for the buggy.
My car was dialed all weekend, only thing I have not done is the rear tower. I think I will wait for the new towers that they are working on.
