Also when you have individual blocks like the as3 they squirm against each other causing the tire to overheat and become slippery.

The s-04 vs the as3 is not even in the same league.
Tell why I was able to run 12.9 on my stock Z with the as3 and my best with so4 was 13.1 on the drag strip? Btw I went multiple session/days with both tires
