Paul, I can clarify some points. The RC10/B2/B3 had a different offset than the Losi cars. When AE made the B4, they took the 'Losi standard'.
Now, AE rear = Losi rear = Tamiya rear.
I saw Masami (well, actually, his mechanics) try Losi and AE wheels on the back of his B4 at the Worlds warm-up in Collegno ('05).
So that means two things :
- AE and Losi wheels are close enough for Masami to use them back-to-back.
- They are slightly different (I believe Losi is softer), so it can be a tuning tool for a 14-times world champ
