If you have the time to explain not just the differences between these models but also the reason Kyosho made the changes I would very much like to see it up here.
ZX, ZXR, ZXR mk2, ZXRR, ZXS and ZXS Evo.

Ok I have forgotten the chassis details but most is below. If ive missed off sorry but is a rushed job and please add if not right.
Lazer ZX
Ball diff slipper clutch with one way hub giving a 60/40 drive and was hard to dial but worked well on loose surfaces if you got it right.
Gear diffs
Alloy towers
Chassis weight distribution was mid chassis
ZXR
single top deck
Different steering plate to aid ackerman
Ball diff - more tunable to different surfaces
Shock towers grp and the reason was they were stronger and less prone to breaking
slipper clutch giving a 50/50 balance and proper slipper
Chassis weight distribution was mid chassis
MK2
single top deck but longer
smaller motor plate
chassis weight pushed further back aiding in jumping
Different steering plate to aid ackerman
ZXRR
smaller motor plate
Different towers with more positioning
Hyper clutch making spur gear changes possible by removing two screws unlike the previous models where you had to rebuild the unit to replace the spur.
Chassis same as MK2 but L bace extended to stop flex
ZXS
One piece chassis, top deck, steering plate, towers front and rear, gearboxes front and rear all new. Diffs original ZXRR diffs. Wishbones, hubs front and rear and Ujs and steering from the ZXRR as well as yokomo wheel adaptors and yokomo wheels. Also came with Losi shocks. Servo had one hole in mid chassis so servo had to be glued to get correct steering.
ZXS Evo
Three piece chassis, (kick up plate with brace to attach to the chassis, same top deck, same front and rear towers (team cars had more holes), new hubs front and rear, same ujs, same wishbones, pure ten steering, same steering plate, new design shocks (basically the original version of what you'd call the velvet shocks) hexes and kyosho wheels. also chassis has a hole for the outer servo lug so the servo didnt need to be glued to the chassis.
