RE: Foams
the problem is that rustler wheels are metric, ae is english units. you can easily make the rears fit, but the fronts are a different issue. i have some foams at home i am not using, i will compare those to the pede/rustler shafts and see what we can do to help you. i think i could pretty easily make you a new front axle that will work with rustler gear, but let you run ae tires.
oh wait, the rustler doesnt use wheels with bearing up front...i think there is a very easy fix..
you need to just drill the rim out with a 5mm drill bit.
