Patrick, I've had all three Lazer ZX, Lazer ZX-R and Turbo Optima Mid SE.
It depends on which Optima you are referring to. Some had chain drive,
while the later ones were belt. I do believe the Lazer lines used a wide
stance and a center diff. The ZX-R had a one way center diff as well.
Also, the Optima Mid I have has a Medal chassis, while the Lazer line uses
Graphite. Beyond this I cannot remember because I have sold both the Lazer
ZX and ZX-R on ebay a couple of months ago, but I sill have the Optima Mid
SE.
