pivot points...where things pivot...swivel, turn, spin, etc
See in the first image you posted how the bar connects to the end brace at 1 bolt? That is where the bar will move, with the car - the whole reason why youre getting them in the first place is to reduce flex. If the brace is pivoting at that point, the same as the car flexing, youre wasting your time.

The second bar, in picture 2, has 2 bolting points, which removes a pivot point, where the first in picture 2, has 1 point = pivot. (and no, thats not a real hype arr brace)

Good bars have no bolt locations between the mounting foot, and the bar itself. IE) Mugen, OEM, Neuspeed, PasswordJDM bars
Shitty bars, have bolting points (pivot points). IE) Ebay bars, SPOON, DC, etc
