As James says, the ZX two piece top deck isn't a good idea. It does keep the chassis as stiff as the ZX-R setup, but only if it is run with the chassis spine that lock the gearboxes together. You are just adding more weight and making it harder to work on just for the sake of keeping dust out of the front belt.
As for snapping rear belts, I've never had that problem after running every week for 6-7 years on carpet. I snapped a few early on, when I tried drilling through the ZX centre diff and bolting it together, until I took the balls out and ran it as a slipper. Kept the roller guides on the layshaft as they do stop the belt skipping which damages the pulleys, leading to belt wear. Never had a problem with it running 10-12 turn brushed in it back then, just allow the slipper some movement. It can be tricky finding the sweet spot for the slipper to give under shock loads while still giving full drive, but you just have to adjust the nut by fractions of a turn until you get it right. Had it out again recently running with a 10.5T in it for racing and general bashing...
and still not damaged a belt. I don't think you need to worry too much about it. After all the belts are exactly the same as those in every other modern belt drive buggy.
