Procat belt slip.

Is there a trick to eliminate belt slip without excessively tightening it? I have the stock pulleys front and rear and a new 4,5mm MXL belt. I loosened the front diff so that when I hold the front wheels and try to swing the car up the diff gives before the belt slips, but the belt still slips often while driving. It also sits off to one side of the front pulley and won't go to the center. I bought a used MMS (I think) front diff which will at least help with the centering, but I suspect it's slipping in the rear as there's less wrap around there. I guess I'll find out when I get the new front diff. Maybe the rear diff is worn, though it didn't look like it was when I had it apart some time ago. I want to avoid a slipper clutch.

If I can't get it to work and want to keep driving it I might mill new diffs for GT2 3mmm belts out of Delrin.
