what is the difference in this and the 25.1 and 25.2.

Small changes or too BIG to describe here?

What ET/MPH is the 25.3 good to?

Is that the SFI your building my chassis to?

I always thought SFI and NHRA/IHRA worked together to set these standards? Makes no since that IHRA would have already adopted it and NHRA is still dragging their feet.
