Well, without you being a wise$$, that's pretty much right on. The only thing I would add, and w/o being a wise-a$$ myself, is that AC made changes and improvements as well based on their own testing/racing. Their (AC) involvement in racing wasn't to the extent of SAI for sure but there were improvements made to the cars non the less. Racing improves the breed. (Wish I knew who said that!)
