I don't understand why ITR will be so much more expensive than ITS or even ITA for that matter. Especially for me in a Z3. Could someone help me understand why this class will be sooo expensive. I mean I understand bigger tires but that is only 500 a season more (maybe?). Isn't everything all relative. Shoot you need 30K+ to run at the front of A or S why would R be so different? I guesss running an ITA Z3 has left me immune to the financial hardship argument.
