Standard arms and the M sport arms are very different.

The ZHP's arms and the M Sport II arms are the same. They are beefier than standard control arms and use metal lined ball joints.

The picture was more for reference than anything else. (Although in the image breakdown, item 5 is the control arm. #5 has 2 options, M Sport II or standard. Though the picture of the control arm is standard and used for both versions, the difference between be 2 is substantial).
