Nothing new. I recall the ever changing P/S weight breaks in the 70's when one combo was dominant over the others.

But this class is already a train wreck. Allow a super secret motor in the Challengers that you can only buy if you're in the "inner circle" from ONE shop, then add weight when that combo outruns all others. Then when the others out run that combo, you slow the blowers down???

Sounds like the NHRA circus has new clowns via this class.
