wow, no... not on my mustang. few things to note. square will always prevent flex more then round due to its geometric strength of having vertical side walls. second going underneath the cars subframes, while hurting ground clearance slightly, is the best way to prevent flex, as its effectivly making the subframe TALLER and adding more of a sidewall length (again the reason for the square) that prevents flex.
also looing at the design it looks like its supposed to be welded only at those flat supports that go on the bottom, which will be where the flex would be anyhow... if this is the case (didnt see any install instructions to prove me right or wrong) then you might as well not have them as the welds will either brake or the tabs will bend.
not trying to hate on them, but come on.... if you are spending 130 on those then just drop the extra 10 and get the MM XL FLSBCs.... thickest, longest, and square. plus every torque arm on the market can bolt up to square brace... which you might not care about.... but look at it this way, why would the torque arm prefer the square over the round.. shape? or just that if going for true solid
suspension they figure you would o with the square... font believe me, shoot a line to MM then, ask what Matt has to say.
on a side note, i think Tom sold his mustang and has an audi now.... had a post a couple weeks ago that mentioned he no longer bleeds ford blue (sold the car) and is playing with quattro (audi's AWD system), so, there is the chance we will never see him again.
