I = Mazdaspeed/ GTR trailing arms
()= ZX2 tubular trailing arms
[]= OEM MX3 trailing arms
[ = maybe MS/GTR???
I know the MX3 ones are of a older design so they are not as strong as the ZX2 arms. BUT I have been told the MS/GTR arms are fairly strong and come in a I beam type configuration. I have found another set that is more of a half I beam which looks like a [ What kind are these? or is there no actual I beam arms and the [ beam arms are MS/GTR arms?????
Between the ZX2 arms and the MS arms which are stronger??
Is there anything else from the ZX2 i can use on a MX3? i seen the calipers and LCA´s are the same. Maybe the brake booster is of a better design since it is newer as well? I found a few ZX2´s that are pretty mint at my local pick and but no MX3´s

I know both chassis are very similar with the ZX2 having improvments over and MX3 because of its age.....
