Now my center diff spins freely, but new problem comes up. This time it's the pinion's turn to touch the mount. I have to pull the pinion 1mm farther away from the motor to let it run free. WTF do they design it this way. I coundn't use the plastic spur's full teeth width, only 4/5 width is contacting the pinion.
The fact is, Losi designed the plastic spur so wide that it almost get conflict with the mount, but that extra width can NOT touch the pinion, it does not work together with the pinion, which is what it was designed so wide for. Is that logical ?
Yesterday I managed to run my 8ight 2.0 E conv, finally. It did run great but I just can't say it was a perfect design.

after reading your post, i just went and looked at a couple of my plastic spurs.....they don't all seem to be exactly the same width. I wonder why this is?
Still, if you get the RCM mount, you'll have zero issues with rubbing on the chassis as it raises the center diff a few mm and i don't get any rubbing on the mount from the spur either. I run 45T with no problems at all. Not only that, it's an awsome mount that allows you to gear as high or low as you want. that's one thing that no other 8ight conversion seems to offer right now.
the wheel freespin i get is crazy...no binding at all. RCM mounts rule!
