Cut every other or every 2'nd and 3'rd tooth off the belt, sand down some material off the top of the belt, soak in rubbing alcohol, there are more, I'll post em if I remember them.

try dremeling the diff cases just a little bit where the bearing sit. like on the tc3 is keeps the bearing from binding up inside the diffcase. this would apply to the xxxs, and thats about it lol

Well i was told you really dont need to cut any teeth off the xray belts. And it comes free as well. Just My opinion, i have never tried cutting the teeth on the xray belts.

Do you want them looser? or just to roll free?

What are your belt settings at?? Are they on Loose on the bulkheads??

I have heard to take the belts and stretch them out. (put it on your foot and pull.)

cutting every other tooth on a belt is something losi specific as the internal ratio (the diff/centre pully relationship) is slightly off and will cause the belt to skip every so often cutting the teet on the xxxs reduces this.
on most other cars its just weakeaning the belt...

I cut every other tooth off on the belts for my Mi2 and it helped a little. The belts dont always need to be loose to be fast. Schumacher said they are getting better lap times with belts set right than set loose. The belts are the same as an automotive timming belt. They are made not to stretch, to hold a consistant length at all times. I have been setting mine so that the slack is taken up but not to the point of putting tension on the belt. They have been working great for me that way.
