Alright, I must have built mine wrong them because the drivetrain had alot of drag in it. Even with an overgeared 19t I couldnt hang with the Xrays. I'll give your car a tray. Just waiting for some pictures...
If you don't have the center diff/gears perfectly shimed you get a little binding, which in turn makes drag, and in turn makes belts go bye bye LOL I had to learn the hard way. The drive train on the Trade seems to binding free.
Let me Know,
