so no pictures of the broken ruca??? I may be thinking wrong here, but if i hit something shit is going to bend. I would personally rather a $120 arm break rather than bend something that is not as easy to replace(frame mounting point, knuckle)

Traditionally control arms and end links are actually designed to be fairly ductile in order to translate the impacts into bending less expensive components such as the links/control arms themselves than your knuckles and frame. That and having a ductile material also allows the product to bend rather than snap when deformed, allowing you to move your misaligned vehicle from the scene rather than loosing all control haha.

So technically, stronger isn't necessarily better, it is the marriage of strength vs. ductility, and of course dont forget weight!

UPDATE 03-2014:
So almost 3 years later and the arms are holding up just fine! Car has been daily driven everyday since putting all the Circuit Sports arms on and theyve held up great! Ive since changed coilovers though. I swapped the CS coils for Fortune Auto 500 series as the FA's go much lower and are just an all around better product. Though, again, I will say that the CS Coilovers were a great entry level and affordable coilover. When I sold them, they were almost 2 years old and had zero signs of any problems! The CS coils were daily driven everyday as well so I can attest that Circuit Sports suspension parts are pretty damn decent for everyday use. How they hold up to heavy track duty, Im not 100% sure on, but if the wear and tear of everyday driving is any sign of quality, I bet they hold up just as well on track!
