Here is some light reading on my experiences with the rear AP1 rear toe curve.

Track driving both the bone stock AP1 and the modified BSK/alignment AP1, here are the differences as I see them:

The stock AP1 setup really rewards smooth driving, being gentle on the inputs, especially braking.
Hitting curbing or track pot holes under lateral load, affected the stock car more. You were ready to make that small steering correction at all times.
Overall I liked the oem setup, but you had to be ready to respond to what the chassis does. For me it was fine, but I can see a ham fisted driver getting into trouble.

The modified setup also included a more aggressive alignment and coilovers so it is difficult to pinpoint the exact cause. But from the before and after on just the BSK, I remember, the car needed less input maintenance to hold a line. Transition trail braking, no longer provoked overrsteer. Hitting curbing did not upset the car as much.

I would consider myself a smooth but not terribly aggressive driver. I had many more tail out experiences with the OEM setup, however I always felt in control, and even can be fun. With the new BSK setup, the only tail out experiences I have had are slow 2nd gear power oversteers. Even then they have been VERY controllable. The car is ultimately easier to drive more aggressively. With the BSK, DFV and track alignment, I can't think of one bad trait. The car doesn't really understeer or oversteer and you can just hammer it through pretty much anything. I have even made some purposeful mistakes, like mid-corner throttle chops just to see if the car would get loose... nope. My challenge now is just upping my aggressiveness to get more out of the car.
