Guys thanks for the help - I am really confused here by some of the answers you gave me and, let me tell you why:
just talking rear wheels here - I tried in the past to run XXX wheels on a B3 (or the other way around, can't exactly remember as it was years ago) and it didn't work - the wheel was hitting the arm. So my understanding is that Losi and AE rear 2WD wheels don't mix.
I also believe that B4 and B44 rear wheels aren't the same again - different offsets, so one can't really talk about "AE rims" in general. At best the track isn't standard anymore and the dimenssion/suspension cinematics are off, at worst again it doesn't "fit".
I'm not trying to be a smarta$$ or anything, but I would just like to make sure, so please bear with me and forgive me for being such a PITA: "do the losi rear XXX rims have the same exact ( ie <2mm difference if any) offset as the 501X/Durga rear wheels"?
Thanks to those patient enough to help me
Cheers,
Paul
