I think the trick to getting this part to set right is in how you get the bearing on the spur side to fit.. what I mean is there is play on the bearing so it moves back and forth just a little bit, if you don't get it perfect into the CNC mount and then kind of pull it out slightly and into the front mount it will not fit properly as you described. I have an 8ight-e 2.0 sitting next to me and it fits just fine using the losi kit and it doesn't rub at all. I would suggest investigating how that bearing is setting (even or not) and you will find that it will work ok for you when you install it correctly. Now I do know you can't use the plastic bearing w/ the tekno kit as the spur rubs into the bottom so you would need to cut out an even bigger spur drop which really isn't worth doing. I really wanted to swap to the plastic spur, but I decided to just hold out w/ the stock steel 48t. I absolutely love how the 8ight-e 2.0's sound w/ the plastic spur gear installed (my brother has one) :)
