Hey JSpeed...would you like to step up and foam a IGT class here on rctech and draw up some guide line about those track that wants to pick up this class?
First, start with the SPEC class with open rubber tires (no foams) and limited option parts (open brand but limited to the specific option parts like 2-speed gear but no centax or shocks upgrade but no alteration of the parts itself...etc)
I am sure alot of us here can help to add or provide opinion about the rule..
