Good point - thanks for pointing that out. I suspect we're talking small differences in alignment strategy, however, based on what I think I remember about threads dealing with autocross alignments between model years. They're not THAT different, are they?

 

When I run 0 rear toe I get oversteer. I need to run about .25 to keep the rear planted so that I can put the power down earlier in the corner.

With that said since you are running a stiffer front bar and have understeer less rear toe might help.

But as others have said, i would have played with the alignment first and then saw what piece$ I wanted to add to go faster.

 

The factory recommended alignments for AP1 vs AP2 differ only in the rear toe: about 1/4" for AP1, about 1/8" for AP2. Small, but significant.
