In talking with bob at the halloween classic and the novak , i did ask him a few questions and one was about the chassis and top decks, cause until the classic i hant seen the top deck they were running there. In the early pictures of the car they did have the ITF top deck, as they were running rubber tire asphalt ( on oad nats and worlds ). As far as the chassis if i remember right from what bob had said it was just going to be a thinner version of the factory team chassis that comes with the kit. Its been a while so dont quote me on that..
I am sure rick, juho, or brandon would know they have all run rubber tire with the car.
