I was going through the WC Touring Car rules and they seem very close to ITR. Seem welding and attaching the cage to the body look like the big difference in the chasis. I think suspension and engi es are the same but i am not sure... Does anyone have more experience and understand the difference in prep levels. It looks like ITR is actually probably a bit quicker because we dont have a spec tire. If this is all true maybe we should look at these cars as the future of the class...
