when you put the car into LRC mode you raise the rear hanger to keep the same (or close enough) anti-squat. so in HRC the '3' gives 3 degrees, but turn it upside down into LRC and the inverted '1' insert gives 3.3 degrees. I think you can pop the older 2010 #2 hanger on to get back to 3 degrees though?
If that new block gives an even lower RC than the kit one then you'd end up with >3.3 degrees of max squat achieved from the inverted '1' insert and perhaps going to the inverted '2' insert would bring you closer to the original 3 degrees?
If you ran this newer block to give an even higher RC (than kit) then you would need a new rear hanger to keep the 3 degrees using the '3' insert again.
(my question marks are for clarification from TD)
