I am sure one of the many engineers on this forum can do a quick hand calc of a rectangular curved bar under load.

Yes, the factory link is not a rubber bushing but it does have a rubber cover which probably helps the ends last a lot longer.
It could all be in my head but when I didn't feel the rear end getting light about 2/3 of the way around a right turn onto a state highway. That is very subjective. Unless I mount a camera focused on the OEM link its all guess work. I'm not an engineer but the OEM link is a curved H beam (aluminum??) vrs the Dinan link which is a hollow straight rod. I would guess that the dinan link is stronger? Its not an astounding difference. I lucked out and got this pretty cheap used but never installed. Would my feelings be hurt if I had paid $500+ for it? Maybe. I would think that this piece would be of little value if you already have coilovers and numerous other suspension mods.
I don't think this part will really cut the lap times of a professional but it has, so far, made me feel warmer and fuzzier. I think it will cut lap times for inexperienced, non-professionals like myself.
