I appreciate the insight.
Unfortunately, I live in Winnipeg (Canada) where there are probably no more than a dozen BRZ/FRS. On top of that, I can almost guarantee that there aren't any that are boosted. Hence the reason why I'm relying so heavily on what random people are telling me on the internet
I considered an EvoX before pulling the trigger on a BRZ and found the response to be adequate. If the AVO kits are more responsive then I would be happy with it.
