Yeah, I hear you. In the scheme of things, 8 lb. (3.6kg) isn't a lot, but the only way to meaningfully reduce weight requires a lot of little contributions. In that sense -8 lb. is a decent chunk.
I'm curious what the stock arms actually weigh, 8 lb. seems like a lot to remove from parts that aren't that big/massive to begin with... Tube structure is a lot more efficient, but still...
It looks like the heavier end of the control arm is the sprung end, so reduction in unsprung mass will be somewhat less than half the total mass reduction.
Of course it'd be awesomer to remove weight that is high and forward, but these parts are low and aft.
All about benefit vs. risk, cost, $$$, and effort expended!
