Just came home from the dNaNo track near me. I've done everything Lornecherry suggested, and had a decent amount of track to test the setups. Everything Lornecherry suggested really helped cut down on 85% of the chatter. Anyone suffering from chatter problems or handling issues in general should try some of Lornecherry's ideas.
The only thing that I could add would be that Atomic 25s up front and 20s in the rear is a good tire combo for those that like their cars twitchy!

For those who running on carpet, who want just a little more front and rear traction than the stock setup provides, try Kyosho 40s up front and 10s in the rear.
Thanks again Lornecherry.
