Well thats where it gets tricky, as Kyosho sold the cars with different specs, depending upon where they were sold. The biggest difference was that most US kits had graphite chassis, everywhere else they were sold with FRP chassis, though the last 2 versions were sold as graphite chassis only.
Differences are: (and this is just off the top of my head)
ZX - Original Lazer had a third ball diff mounted in the spur gear, big bulky body, and shock towers with huge amount of holes for adjusting shock angles positions.
ZX-R - New body, one piece upper deck , third diff replaced with slipper clutch, lighter arms, shocks towers with only a couple of shock mounting holes, and longer front shocks.
ZX-R MkII - New chassis with cells moved back (which also meant new motor plate and few other bits), redrilled C-hubs for more castor and wider track, and new front shock tower with more holes and more inclined mounted shocks.
ZX-RR - Not too sure about this one, but I believe it was a ZX-R MkII with new slipper clutch and new shocks.
ZX-S - Completely new chassis design featuring kick up front end, open gearboxes with alloy posts between carbon fibre plates, and new steering bellcranks. New upper front arms using tiny turnbuckles (like Yokomo YZ10), Losi shocks included on new towers. New body too (based on the old Optima Mid Custom)
ZX-S Evo - As above but with Kyosho newest shocks and white rims. Not sure of any other changes.
