Like ProtegeSTS has said before, get the GC`s for the zx2, since the Mx3 strut seem to be narrower than the zx2. And also as a recommendation, do as ProSTS says and figure out what spring rate you want(how to determine that is beyond my knowledge) because the rate in the springs they send you are for racing purposes and are pretty stiff.
To give a little more information about road conditions, think of Mexicali as the location where they filmed the comet scene in "Armagedon".
Here we dont have pot holes, they would be better described as craters.
Personaly i didnt like how the tockicos performed, but consider i drive under extreme road conditions. When i was coming form San Diego to Mexicali, however, the roads were pretty flat and easy on my suspension and it performed quite well. I could take corners as fast as 110 MPH without loosing control or traction, but i simply cant use it on Mexicali where i drive daily because of the sh*tty roads. Feel free to ask anything
