I can't confirm if Losi 56 pistons are = to AE but I can tell you that the number refers to the size of the drill bit that is used to make the hole. AE number 2 is a 56. so I believe it's 1 55, 2 56, 3 57 but I always get 1 and 3 backwards LOL. That's what I get for running 2's everywhere (and why I keep a manual in my pit box :P)
as far as limiters... they affect your weight transfer alot. I am a bit rusty on the details for that too, but I know that you definitely want to look at that aspect of it as well. If you can't find anything, shoot me a PM so I remember to get the info for you tonight. I know I have it saved somewhere at home
