I don't like those arms because they are skinniest in the center; where the maximum bending moment and contact will occur. They are also aluminum, which I am trying to get away from, although it is 6061. I will be happy with my cheap 4140 alloy lol. I like being able to adjust the bars without jacking the car up, and Im sure the alignment shop would have a much easier time with the bars that wouldn't require the car to come down from the rack every time an adjustment must be made. I will see how the new ones behave, and would like to take measurements when the car is properly aligned.. This way I will make draw the arms in inventor in case I need to cut solid ones at a later date.

and 180.. yes steel is harder than aluminum, I was just being a smartass . My problem is related to the softness of aluminum, and my concern is that the cross sectional area of the bar will decrease, and the bar will bend and eventually break. For a $20 fix (compared to $300+) it makes perfect sense to me.The increased strength would allow a smaller cross sectional area, so I can turn the bars down a little for added clearence while keeping them stronger than 6061 aluminum; or even stainless steel, which other top of the line bars are made from.
