Honest question which may be answered by Andy's answer...

Why can the S2000 run at ITR spec but the RX8 has to add weight? Why can't I run my RX8 as an ITR car?

PS: Jake you are spot on for IT gains and stock they have 170-180. Biggest issue with any Rotary Dyno number is that none are really set up for them specifically so the user error is pretty high.
